I was working on a distribution recently where `python` was mapped to `python2`. It mixed me up for a bit since I was writing a script for `python3` but it ran partially under `python2`. To lower confusion in the future, I think it's a great idea to check the python version and exit if it isn't the version you expect.
|
|
|
|
```python
|
|
from sys import version_info, exit
|
|
|
|
if version_info.major != 3:
|
|
print("This script only supports Python 3")
|
|
print("Curent version: " + \
|
|
str(version_info.major) + "." + \
|
|
str(version_info.minor) + "." + \
|
|
str(version_info.micro)
|
|
)
|
|
print("Exiting...")
|
|
exit(1)
|
|
```
