How to remove each element from a string in python?

Question

I want to remove each element from a string. For example: s= "abcde" now I want to remove first "e" then "d" till s is empty.

Answer 1

You can use slices:

s = 'abcde'
for i in range(len(s), 0, -1):
    print(s[:i])

Answer 2

You should use slice operator as:

s='abcde'
for i in range(len(s), -1, -1):
    s = s[:i]
print(s)

Output: ''

Answer 3

s = 'abcde'
c = list(s) # this line converts the string to array of 
                  # characters [ 'a', 'b', 'c', 'd', 'e'] 


while c:   # loop till array is empty
  c.pop() # Retrieve elements from the array end and 
                # remove it from array 

Output:

'e'
'd'
'c'
'b'
'a'
