chr() and ord() in python

ord():Returns the integer for specified symbol.

chr(): Return the symbol for specified integer value.

Note: To understand the functionality of chr() and ord() functions, we need to know the values of ASCII character set.

ASCII : (Americans Standard Code for Information Interchange)

We can check the values directly at shell window as follows:

>>> chr(65)
'A'
>>> chr(50)
'2'
>>> ord('a')
97
>>> ord('$')
36
>>> ord('1')
49

We can write programs at editor window as follows:

sym = input("Enter symbol :")
num = ord(sym)
print("The value is :", num)

Output:
Enter symbol :$
The value is : 36

num = int(input("Enter number :"))
sym = chr(num)
print("The symbol is :", sym)

Output:
Enter number : 65
The symbol is : A
