Ways to increment a character in Python
In python there is no implicit concept of data types, though explicit conversion of data types is possible, but it not easy for us to instruct operator to work in a way and understand the data type of operand and manipulate according to that. For e.g Adding 1 to a character, if we require to increment the character, an error instructing type conflicts occur, hence other ways need to be formulated to increment the characters.
Python
# python code to demonstrate error# due to incrementing a character# initializing a characters = 'M'# trying to get 'N'# produces errors = s + 1print (s) |
Output:
Traceback (most recent call last):
File "/home/fabc221bf999b96195c763bf3c03ddca.py", line 9, in
s = s + 1
TypeError: cannot concatenate 'str' and 'int' objects
Python3
# python code to demonstrate way to# increment character# initializing characterch = 'M'# Using chr()+ord()# prints Px = chr(ord(ch) + 3)print ("The incremented character value is : ",end="")print (x) |
Output:
The incremented character value is : P
Explanation : ord() returns the corresponding ASCII value of character and after adding integer to it, chr() again converts it into character.
Python3
# python code to demonstrate way to# increment character# initializing byte characterch = 'M'# converting character to bytech = bytes(ch, 'utf-8')# adding 10 to Ms = bytes([ch[0] + 10])# converting byte to strings = str(s)# printing the required valueprint ("The value of M after incrementing 10 places is : ",end="")print (s[2]) |
Output:
The value of M after incrementing 10 places is : W
Explanation : The character is converted to byte string , incremented, and then again converted to string form with prefix “‘b”, hence 3rd value gives the correct output.
