New submission from William Barnhart <[email protected]>:
An issue I encountered recently with argparse was when I tried running a script
with its argument changed from something like:
```
parser.add_argument('--please_work')
```
and was replaced with:
```
parser.add_argument('--please-work')
```
I have not ever seen anyone add an argument where a function has two arguments
existing in a function, such as please_work and please-work. I think this is a
pretty safe feature to implement, plus it enforces good practices. So if I
wrote something such as:
```
parser = argparse.ArgumentParser(description="check this out")
parser.add_argument('--please-work')
```
Then I could call the program using:
```
python3 test.py --please_work True
```
or:
```
python3 test.py --please-work True
```
