To use integer data in our program when it is passed as space separated integers, we need to convert the string input to integer after splitting them using Python string split operation . 'Base' specifies the base in which string . These types are namely: int, str, float and bool. But you did not pass argument base=16 in the int() function. This uses the prefix to determine the base automaticallywithout you needing to set it to 16. First we have to declare a variable specifying its data type in our case int then name of the variable. And heres how you can convert the additional examples shown above: You actually dont need to use the prefix '0o' because your second argument already defines unambiguously that the given string is an octal number: However, skipping the base but leaving the prefix raises a ValueError: invalid literal for int() with base 10: '0o77': It assumes that the input string is in base 10 when in fact, it isnt.

For example: converting integer data to string. If you have a decimal integer represented as a string and you want to convert the Python string to anint, then you just follow the above method (pass the string to int()), which returns a decimal integer.But By default,int()assumes that the string argument represents a decimal integer. It is not a function. int (a, base) This function converts any data type into integer. If a string is provided instead of a number, str () returns the string itself. We have to keep in mind that converting a string data type to int data type is not as simple as type casting where we can easily convert double to int or vice versa. To convert the integer to float, use the float () function in Python. In this example, we did a variable declaration named x. The way to specify the number system is to usebase: Now,int()understands you are passing a hexadecimal string and expecting a decimal integer.
