How do I convert a string to a number?..

Answer / chaitanya

Python contains several built-in functions to convert values from one data type to another data type.

The int function takes string and coverts it to an integer.

>>>s = "1234" # s is string

>>>i = int(s) # string converted to int

>>>print i+2

-------------------------

1236

The float function converts strings into float number.

>>>s = "1234.22" # s is string

>>>i = float(s) # string converted to float

>>>print i

-------------------------

1234.22
