Hello, all. In python, I don't know how to convert a string into an uppercase. I thought string.ascii_uppercase will work, but it doesn't.
Look at the following code:
>>s = 'sdsd'
Ultimately, it gives a error message:
Traceback (most recent call last):
File "<console>", line 1, in <module>
AttributeError: 'str' object has no attribute 'ascii_uppercase'
Anyone, please help me, guys.
