# capturepy
Capturepy captures the standard output and the standard error of functions, methods and any blocks of code. It is useful when testing, debugging and working with libraries.
### Install
`pip install capturepy`
It requires python 3.8 or higher.
### Usage
See the examples.py file for a complete list of examples.
This module is based on the class Capture, which can be use as a decorator, or with the 'with' statement.
Here are some examples:
##### Capturing output of function
```python
from capturepy import Capture
print('Capture stdout and stderr of function using the Capture decorator.')
@Capture
def my_func(x):
print('first')
print('second', end='', file=sys.stderr)
return x**2
output, result = my_func(4)
print('The captured output is:')
print(output)
print('The function returned:')
print(result)
```
##### Capturing only standard error of code using "with" statement
```python
from capturepy import Capture
print('Capture only stderr of code using the "with" statement.')
with Capture(stdout=False) as capture:
print('first')
print('second', end='', file=sys.stderr)
stderr = capture.get()
print('The captured stderr is:')
print(stderr)
```
