# Conditional Operator Inverter
This script inverts the conditional operators in a given Python code snippet. It uses the `ast` module to parse the code and a custom `NodeTransformer` class to invert the operators.
## Prerequisites
Before running the code, please make sure to install the required `astor` package by running the following command:
```sh
pip install astor
```
## Usage
The script takes a Python code snippet as input and inverts the conditional operators in the code. It includes automated tests to verify the correctness of the inversion.
### Example
Here is an example usage of the script:
```python
example_code = """x = 10
y = 5
while x <= 0 and x < 0:
x = x + 5
print("x increased by 5")
if x >= y and x != 0:
print("x is greater than y and x is not zero")
else:
print("x is less than y or x is zero")
"""
# Process the code
operator_positions, inverted_code = invert_conditionals_and_output(example_code)
# Print the results
print("\nOperator positions:", operator_positions)
print("\nInverted code:\n")
print(inverted_code)
```
### Output
The script will output the positions of the inverted operators and the transformed code with the inverted operators.
## Automated Tests
The script includes automated tests to verify the correctness of the inversion. The tests can be run by calling the run_tests function.
### Example Tests
```python
def test_inversion():
test_code = """if x < y:
pass
if x != y:
pass"""
expected_operators = [((1, 3), 'Lt'), ((3, 3), 'NotEq')]
expected_code = """if x >= y:
pass
if x == y:
pass"""
positions, inverted = invert_conditionals_and_output(test_code)
assert positions == expected_operators, f"Expected {expected_operators}, got {positions}"
assert inverted.strip() == expected_code.strip(), f"Expected:\n{expected_code}\nGot:\n{inverted}"
print("All tests passed!")
def test_nested_conditions():
test_code = """if x < y and y != z:
pass"""
expected_operators = [((1, 3), 'Lt'), ((1, 13), 'NotEq')] # Updated column position
expected_code = """if x >= y and y == z:
pass"""
positions, inverted = invert_conditionals_and_output(test_code)
assert positions == expected_operators, f"Expected {expected_operators}, got {positions}"
assert inverted.strip() == expected_code.strip(), f"Expected:\n{expected_code}\nGot:\n{inverted}"
print("Nested conditions test passed!")
def test_no_conditions():
test_code = """x = 5
y = 10
print(x + y)"""
expected_operators = []
expected_code = """x = 5
y = 10
print(x + y)"""
positions, inverted = invert_conditionals_and_output(test_code)
assert positions == expected_operators, f"Expected no operators, got {positions}"
assert inverted.strip() == expected_code.strip(), f"Expected:\n{expected_code}\nGot:\n{inverted}"
print("No conditions test passed!")
# Run tests
def run_tests():
test_inversion()
test_nested_conditions()
test_no_conditions()
