Convert String into Float in Python

We cannot use mathematical operations on a string in Python programming. To do so, we have to convert a string containing numeric value into a float or any number. Most of the time we get data through text field or by reading a text file. Usually, entered data is received as a string. For doing mathematical or statistical calculations, we have to convert or parse the string (“numeric value in a string”) to a numeric value such as float.

Look at the following example for more understanding.

Example # 1

555.55

Example #2
