Python string to float/int conversion: easy parsing guide

Converting a string to a float or integer is a common task in Python programming. Fortunately, Python provides built-in functions for simple string parsing and conversion. In this guide, we'll show you how to easily convert a string to a float or integer in Python.

Converting a String to a Float

To convert a string to a float in Python, we can use the built-in float() function. This function takes a single argument, which is the string we want to convert:

>>> float_string = "3.14"
>>> float_number = float(float_string)
>>> print(float_number)
3.14

As you can see, we first assigned the string "3.14" to the variable float_string. We then used the float() function to convert this string to a float and assigned the result to the variable float_number. Finally, we printed the value of float_number, which is 3.14.

Converting a String to an Integer

To convert a string to an integer in Python, we can use the built-in int() function. This function takes a single argument, which is the string we want to convert:

>>> int_string = "42"
>>> int_number = int(int_string)
>>> print(int_number)
42

Similar to converting a string to a float, we first assigned the string "42" to the variable int_string. We then used the int() function to convert this string to an integer and assigned the result to the variable int_number. Finally, we printed the value of int_number, which is 42.

Conclusion

Converting a string to a float or integer in Python is a simple task that can be accomplished using the built-in float() and int() functions. By following the examples in this guide, you should now have a better understanding of how to easily parse and convert strings in Python.
