Python defines type conversion functions to directly convert one data type to another. This article is aimed at providing the information about converting a string to int and int to string.
Converting a string to an int
If we want to convert a number that is represented in the string to int, we have to use the int() function. This function is used to convert a number in given base to decimal.
Syntax: int(string, base)
Parameter :
string : consists of 1’s and 0’s
base : (integer value) base of the number.
Example:
# string data n = '321'
print('Type of num is :', type(n))
# convert using int() n = int(n)
print('So Now, type of num is :', type(n))
|
Output:
Type of num is : <class 'str'> So Now, type of num is : <class 'int'>
Converting an Int to string
Converting an int datatype to string can be done with the use of str() function.
Syntax: str(object, encoding=’utf-8′, errors=’strict’)
Parameters:
object: The object whose string representation is to be returned.
encoding: Encoding of the given object.
errors: Response when decoding fails.
Example:
hdv = 0x1eff
print('Type of hdv :', type(hdv))
# Converting to string hdv = str(hdv)
print('Type of hdv now :', type(hdv))
|
Output:
Type of hdv : <class 'int'> Type of hdv now : <class 'str'>
