How to change the class of elements in a list?

I have a string for input with comma seperated elements. - marks = 'marks1,marks2,marks3' Using split function I got list of marks. - marks = marks.split(',')

This gives us 'marks' a list with elements as srting however I want integers as elements. marks[int]

Do we have an in-built function to convert the same or do we need to use the following for-loop?

for i, m in enumerate(marks):
    marks[i] = int(m)

The above loop works but I just want to know if we have some in-built function

Solution

  • If your string is 'marks1,marks2,marks3', you can't convert it directly to integers by casting, as it contains non-numeric characters.

    But, if you used it to explain your problem and string is actually like '31,78,45', you can convert it to a list of int with list comprehension:

    marks = [int(m) for m in marks]

    marks = '31,78,45'
marks = marks.split(',')
marks = [int(m) for m in marks]
