Unable to Catch Exception and Raise Error in Python-CodePudding

Suppose that I have a variable initial_cash = 'a'. I want to check if this is convertible to float else I want to raise error for that I've written code below:

initial_cash = 'a'
try:
    initial_cash = float(initial_cash)
except TypeError:
    raise TypeError("Initial cash amount should be float or int")

I am unable to raise exception instead I get ValueError: could not convert string to float: 'a'. What am I doing wrong due to which the expectation is not caught?

Your answer is in the error message - ValueError. you should expect ValueError instead of TypeError.
