Python ord() Function

The ord() function is  used to return the Unicode integer code of a specified character. The function takes a string containing a single character as its only argument.

syntax:

ord(character)

print(ord('a'))
print(ord('n'))
print(ord('z'))

for i in 'Python':
    print("{} : {}".format(i, ord(i)))

The argument given should strictly be a single character.

ord('Python')

The chr function serves the opposite purpose, where you give it an integer argument and it returns the unicode character represented by the integer.
