### Create IntFlag from Integer

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/E3Types/IntFlags.ipynb

Shows how to create an IntFlag instance directly from an integer, such as one returned from COM functions. The example uses BomType1(12345) and prints its representation.

```python
random_int = 12345
flag_from_int = BomType1(random_int)
print(f"Flag created from integer {random_int}: {repr(flag_from_int)}")
```

```text
Result:
Flag created from integer 12345: <BomType1.EXP_BOM_DEVICE|EXP_BOM_TERMINAL_STRIP|EXP_BOM_ASSEMBLY|EXP_BOM_ASSEMBLY_PART|EXP_BOM_CWI_PART|EXP_BOM_CABLE_DUCT: 12345>
```

--------------------------------

### Work with COM objects

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/Basics/basics.ipynb

Example of working with COM objects: create a job, get sheet IDs, and iterate over sheets. Note that lists/tuples are 0-based, [out] parameters are returned in a tuple, and [IN] array parameters are lists.

```python
job = e3.CreateJobObject()
ret, allSheets = job.GetSheetIds()  # Multiple return parameters, if the return value is not needed you could also call job.GetSheetIds()[1]
sht = job.CreateSheetObject()
for shtId in allSheets:
    sht.SetId(shtId)
    sheetName = sht.GetName()
    print(f"Sheet with ID {shtId} is named {sheetName}.")
```

--------------------------------

### Use python -m pip if pip is not found

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/EnvironmentSetup/README.md

If pip is not found, prefix the command with 'python -m' to run pip as a module. This is a fallback for environments where pip is not directly accessible.

```bash
python -m pip install ...
```

--------------------------------

### IntFlags Bitwise Operations with BomType1

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/E3Types/IntFlags.ipynb

Shows how IntFlags like BomType1 support bitwise combinations and operations. The example prints flag values, combines flags with OR, and demonstrates bitwise inversion, AND, OR, and XOR. Useful for understanding how IntFlags behave like int-backed enums with multiple values.

```python
from e3series.types import BomType1, BomType2

# Flag-value relation:
print(f"Value of {BomType1.EXP_BOM_DEVICE.name}: {BomType1.EXP_BOM_DEVICE.value:#0{10}x}")
print(f"Value of {BomType1.EXP_BOM_CONN.name}: {BomType1.EXP_BOM_CONN.value:#0{10}x}")
print(f"Value of {BomType1.EXP_BOM_TUBE.name}: {BomType1.EXP_BOM_TUBE.value:#0{10}x}")

# Combination:
combined_flag = BomType1.EXP_BOM_DEVICE | BomType1.EXP_BOM_CONN | BomType1.EXP_BOM_TUBE
print(f"Value of combined flag {combined_flag.name}: {combined_flag.value:#0{10}x}")

# Short Representation for debugging purposes:
print(f"Short representation of combined flag: {repr(combined_flag)}")

# Different bitwise operations are supported:
inverted_flag = ~combined_flag
print(f"Bitwise Inversion: {repr(inverted_flag)}\n(Hex: {inverted_flag.value:#0{10}x})")
print(f"Bitwise AND with EXP_BOM_DEVICE: {repr(combined_flag & BomType1.EXP_BOM_DEVICE)}")
print(f"Bitwise OR with EXP_BOM_ASSEMBLY: {repr(combined_flag | BomType1.EXP_BOM_ASSEMBLY)}")
print(f"Bitwise XOR with EXP_BOM_CONN: {repr(combined_flag ^ BomType1.EXP_BOM_CONN)}")
print("etc.")
```

```text
Result:
Value of EXP_BOM_DEVICE: 0x00000001

### Print BomType of All Devices

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/E3Types/IntFlags.ipynb

Iterates over all device IDs in the project, retrieves each device's BomType using GetBomType, formats it with the helper, and prints and logs the message. Requires an active E3.series application and job/device objects.

```python
import e3series

app = e3series.Application()
job = app.CreateJobObject()
dev = job.CreateDeviceObject()

(ret, all_devices) = job.GetAllDeviceIds()
if ret == 0:
    print(f"Error getting all device IDs: Return code {ret}")
    exit(1)

for dev_id in all_devices:
    dev.SetId(dev_id)
    device_name = dev.GetName()
    message = f"BomType of {device_name}: {format_bom_type(dev.GetBomType())}"
    print(message)
    app.PutMessage(message)
```

```text
Result:
BomType of -Q1: BomType1: EXP_BOM_DEVICE|EXP_BOM_COMPONENT (0x00400001), BomType2: None (0x00000000)
BomType of -B1: BomType1: EXP_BOM_DEVICE|EXP_BOM_COMPONENT (0x00400001), BomType2: None (0x00000000)
BomType of -F1: BomType1: EXP_BOM_DEVICE|EXP_BOM_COMPONENT (0x00400001), BomType2: None (0x00000000)
BomType of -M1: BomType1: EXP_BOM_DEVICE|EXP_BOM_COMPONENT (0x00400001), BomType2: None (0x00000000)
BomType of Wires: BomType1: EXP_BOM_CABLE|EXP_BOM_SYSTEM_CABLE (0x08000040), BomType2: None (0x00000000)
BomType of -W1: BomType1: EXP_BOM_CABLE|EXP_BOM_COMPONENT (0x00400040), BomType2: None (0x00000000)
```

### Connect to E3.series and get BOM as array

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/PartsWithPandas/PandaParts.ipynb

Connects to an E3.series instance, creates a job object, and retrieves the BOM part list. If no job is open, the script exits. Prints each BOM line.

```python
import e3series

e3 = e3series.Application()                                 # Connect to that instance
job = e3.CreateJobObject()                                  # If no job is open we exit the script  
bom = job.GetBomPartList("", "4.1", 0, "", "", "", [""])[1] # Get the BOM from E3.series

for line in bom:
    print(line)
```

--------------------------------

### Using enums from e3series.types

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/Basics/basics.ipynb

Example of using the ItemType enum from e3series.types. Enums are helpers; pass Enum.value to functions. This example requires at least one group in the open project.

```python
_, groups = job.GetGroupIds()
grp = job.CreateGroupObject()
grp.SetId(groups[0])        # requires at least one group in the open project
for item in grp.GetItems()[1]:
    itemType = e3Types.ItemType(job.GetItemType(item))
    print(f"The item {item} has the item type {itemType.name}")
```

--------------------------------

### Check Python interpreter path in PowerShell

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/CommonProblems/README.md

Use this command in a PowerShell (not as administrator) to see which Python interpreter is used. The output shows the path to the command, which helps identify the active Python installation.

(Get-Command cmd).Path
```

--------------------------------

### Check Python interpreter and version in E3.series

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/CommonProblems/README.md

Use this script to identify which Python interpreter and version E3.series is using. It requires the e3series package and an active E3.series application. If e3series is not available, replace e3.PutMessage with print() and run with python.exe instead of pythonw.exe, adding a sleep or input to see the output.

```python
import e3series 
import sys
python_exec = sys.executable
python_version = sys.version
e3 = e3series.Application()
e3.PutMessage(f"Python:        {python_exec}")
e3.PutMessage(f"Version:       {python_version}")
```

--------------------------------

### Format BomType from GetBomType

Source: https://github.com/zuken-e3-gmbh/e3seriespythonexamples/blob/main/E3Types/IntFlags.ipynb

Defines a helper function that takes the tuple returned by GetBomType and formats the BomType1 and BomType2 values into a human-readable string. It handles error return codes and prints the flag names and hex values.

```python
def format_bom_type(GetBomTypeReturn: tuple[int, tuple[int, ...]])-> str:
    return_code = GetBomTypeReturn[0]
    bom_type = (BomType1(GetBomTypeReturn[1][0]), BomType2(GetBomTypeReturn[1][1]))
    if return_code < 0:
        return f"Error: Return code {return_code}"
    msg = f"BomType1: {bom_type[0].name} ({bom_type[0].value:#0{10}x}), BomType2: {bom_type[1].name} ({bom_type[1].value:#0{10}x})"
    return msg
