The python upper function is a built-in function in Python that is used to convert all lowercase letters in a string to uppercase. It does not modify the original string; instead, it returns a new string with all the lowercase letters converted to uppercase. The upper() function is part ...
Python’s upper() function converts all the lowercase characters in a string to uppercase characters and returns the modified string. One common application of the upper() function in Python is to check if the given two strings are the same or not. We’ll show you how to do this using...

2 Create a function that will return another string similar to the input string, 3 but with its case inverted. 4 For example, input of "Mr. Ed" will result in "mR. eD" as the output string. 5 ''' 6 import string 7 uppercase = string.ascii_uppercase ...
By default, sys.breakpointhook() calls pdb.set_trace() expecting no arguments. In this case, it is purely a convenience function so you don’t have to explicitly import pdb or type as much code to enter the debugger. However, sys.breakpointhook() can be set to some other function and...
We’ll show you how to do this using an example later in the post. Note: If you want to convert all characters in a string to uppercase, use the Python function upper(). And if you want to swap between lowercase and uppercase, use the swapcase() function in Python. The lower() ...
In this case, we are asking it to display an error, and Python will assume it should return a code of 1 (error encountered) since we have done this. We can use any number in this function if we want to make custom error codes. Once we have assigned our remaining list items into ...
