It is important to be specific about what exception you're trying to catch when using a try/except block.
string = "abcd"
try:
string_int = int(string)
print(string_int)
except ValueError:
# Handle the exception
print('Please enter an integer')
Try/Excepts are powerful because if something can fail in a number of different ways, you can specify how you want the program to react in each fail case.

Here it is:
s = "123"
try:
i = int(s)
except ValueError as verr:
pass # do job to handle: s does not contain anything convertible to int
except Exception as ex:
pass # do job to handle: Exception occurred while converting to int

Think not, but you may implement your own:
Copydef safe_cast(val, to_type, default=None):
try:
return to_type(val)
except (ValueError, TypeError):
return default
safe_cast('tst', int) # will return None
safe_cast('tst', int, 0) # will return 0

October 2, 2024 -
Hello Everyone,
I was wondering if it's possible to get the input of a string from the user and convert it into an integer later on. I'm asking this as the code I'm working on requires a string input from the user of what service they'd like. I later had to add up the totals of the services and wondered if once the choice was selected or inputted then if it would become a number that later adds up to the total cost if multiple services are inputted.
