How can I convert the two other elements in the list from str to int?

Question

a = [1, "2", "3"]
print(type(a[0]))
print(type(a[1]))
print(type(a[2]))
output:<class 'int'>
<class "str">
<class "str">

Answer 1

int( a[1] )
int( a[2] )

by map :

a = [1, "2", "3"]
a = list( map(int,a) )
print(a)

Answer 2

Shantanu ,

you can do this by using a for loop, so that the replacement can be done in-place. to replace the current *str number* by an *int number*, we need the index of each list item.

this can be achieved by using enumerate() inside the for loop:
...
for ind, num in enumerate(yourlist):
...

then use the list name and the index to assign the str numer (has to be converted to int) to the list item
