Removing all commas from list in Python

Question

My issue: I\'d like to add all the digits in this string \'1.14,2.14,3.14,4.14\' but the commas are causing my sum function to not work correctly.
I figured

Answer 1

Since there seem to be a pattern in your input list of floats, this one-liner generates it:

>>> sum(map(float, ','.join(map(lambda x:str(x+0.14), range(1,5))).split(',')))
10.559999999999999

And since it doesn't make much sense joining with commas and immediately splitting by commas, here's a little saner piece of code:

>>> sum(map(float, map(lambda x:str(x+0.14), range(1,5))))
10.559999999999999

And if you actually meant you wanted to sum single digits and not the actual floating-point numbers (although I doubt it since you cast to float in your sample code):

>>> sum(map(int, ''.join(map(lambda x:str(x+0.14), range(1,5))).replace('.', '')))
