Check if the characters of a given string are in alphabetical order in Python
Suppose we have a string s. We have to check whether characters in s are in alphabetical order or not.
So, if the input is like s = "mnnooop", then the output will be True.
To solve this, we will follow these steps −
- char_arr := a new list from the characters present in s
- sort the list char_arr
- return char_arr is same as list of all characters in s then true otherwise false
Let us see the following implementation to get better understanding −
Example Code
def solve(s): char_arr = list(s) char_arr.sort() return char_arr == list(s) s = "mnnooop" print(solve(s))
Input
"mnnooop"
Output
True
