Type Conversion in Python using ord()

Question

s = '4'
c = ord(s)
print ("After converting character to integer : ",end="")
print (c)

output: After converting character to integer : 52

I don't understand the value of output. Can someone please explain why 52 is printed?

Answer 1

If you want become a string into integer you need use the int() function, ord() function returns an integer representing Unicode code point for the given Unicode character.

Example

s = '4'
c = int(s)
print ("After converting character to integer : ",end="")
print (c)

Answer 2

Python’s built-in function chr() is used for converting an Integer to a Character, while the function ord() is used to do the reverse, i.e, convert a Character to an Integer.

For example :

print([(chr(i),i) for i in range(49, 123)])

output is :

[('1', 49), ('2', 50), ('3', 51), ('4', 52), ('5', 53), ('6', 54), ('7', 55), ('8', 56), ('9', 57), (':', 58), (';', 59), ('<', 60), ('=', 61), ('>', 62), ('?', 63), ('@', 64), ('A', 65), ('B', 66), ('C', 67), ('D', 68), ('E', 69), ('F', 70), ('G', 71), ('H', 72), ('I', 73), ('J', 74), ('K', 75), ('L', 76), ('M', 77), ('N', 78), ('O', 79), ('P', 80), ('Q', 81), ('R', 82), ('S', 83), ('T', 84), ('U', 85), ('V', 86), ('W', 87), ('X', 88), ('Y', 89), ('Z', 90), ('[', 91), ('\', 92), (']', 93), ('^', 94), ('_', 95), ('`', 96), ('a', 97), ('b', 98), ('c', 99), ('d', 100), ('e', 101), ('f', 102), ('g', 103), ('h', 104), ('i', 105), ('j', 106), ('k', 107), ('l', 108), ('m', 109), ('n', 110), ('o', 111), ('p', 112), ('q', 113), ('r', 114), ('s', 115), ('t', 116), ('u', 117), ('v', 118), ('w', 119), ('x', 120), ('y', 121), ('z', 122)]

The ord() function takes a string argument of a single Unicode character and returns its integer Unicode code point value. It does the reverse of chr().
