My function needs to take in a sentence and return the sum of the numbers inside. Any advice?

def sumOfDigits(sentence):sumof=0for x in sentence:if sentence.isdigit(x)== True:sumof+=int(x)return sumof

Replace this:

if sentence.isdigit(x)== True:

to:

if x.isdigit():

examples:

 >>> "1".isdigit()True>>> "a".isdigit()False

your code should be like:

def sumOfDigits(sentence):sumof=0for x in sentence:if x.isdigit():sumof+=int(x)return sumof

Some pythonic ways:

Using List Comprehension:

>>> def sumof(sentence):
...     return sum(int(x) for x in sentence if x.isdigit())
... 
>>> sumof("hello123wor6ld")
12

Using Filter, map:

>>> def sumof(sentence):
...     return sum(map(int, filter(str.isdigit, sentence)))
... 
>>> sumof("hello123wor6ld")
12

Using Regular expression, extraction all digit:

>>> import re
>>> def sumof(sentence):
...     return sum(map(int, re.findall("\d",sentence)))
... 
>>> sumof("hello123wor6ld")
12
