The `connect` and `connect_yes`/`connect_no` methods are used to establish the flow, and the final flowchart is printed using `fc.flowchart()`.

```python
from pyflowchart import *

st = StartNode('a_pyflow_test')
op = OperationNode('do something')
cond = ConditionNode('Yes or No?')
io = InputOutputNode(InputOutputNode.OUTPUT, 'something...')
sub = SubroutineNode('A Subroutine')
e = EndNode('a_pyflow_test')

# define the direction the connection will leave the node from
sub.set_connect_direction("right")
    
st.connect(op)
op.connect(cond)
cond.connect_yes(io)
cond.connect_no(sub)
sub.connect(op)
io.connect(e)

```

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

### Control Nested Parsing with `inner` Parameter

Source: https://github.com/cdfmlr/pyflowchart/blob/master/README.md

Explains the `inner` parameter in `Flowchart.from_code`. When `inner=True`, the parser processes the body of a field, creating a nested flowchart. When `inner=False`, the field itself is treated as a single node.

```python
flowchart = Flowchart.from_code(code, field='some_field', inner=True)
```

```python
flowchart = Flowchart.from_code(code, field='some_field', inner=False)
```

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

### Align Consecutive Conditional Statements (CLI)

Source: https://github.com/cdfmlr/pyflowchart/blob/master/README.md

```sh
python -m pyflowchart --conds-align your_script.py
```

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

### Control Parser Behavior with 'inner' (CLI)

Source: https://github.com/cdfmlr/pyflowchart/blob/master/README_zh-CN.md

This command demonstrates the use of the '-i' flag in the pyflowchart CLI to control the 'inner' parameter. '-i' is equivalent to setting `inner=True`, causing the parser to go inside specified fields. Without '-i', `inner` defaults to `False`.

```Shell
python -m pyflowchart --no-simplify example_simplify.py
```

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

### Control Parser Behavior with 'inner' (Python)

Source: https://github.com/cdfmlr/pyflowchart/blob/master/README_zh-CN.md

This Python snippet illustrates the effect of the 'inner' parameter in `Flowchart.from_code`. When `inner=True`, the parser delves into the field's body; when `inner=False`, it treats the entire field as a single node. This affects how nested structures are represented in the flowchart.

```Python
flowchart = Flowchart.from_code(example_simplify_py, field="", inner=True)
print(flowchart.flowchart())
```

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

### Disable Align-Next for Condition Nodes

Source: https://github.com/cdfmlr/pyflowchart/blob/master/README.md
