Convert string to float in python : Sometimes, we need to convert a string to a float value. For example, if you are receiving float data in string format from the server and if you want to do any arithmetic operations on them, you need to convert them to float first.. For example, let's take a look at the below program print(Python is fun.) a = 5 # Two objects are passed print(a =, a) b = a # Three objects are passed print('a =', a, '= b') Output. Python is fun. a = 5 a = 5 = b. In the above program, only objects parameter is passed to print() function (in all three print statements). Hence, ' ' separator is used. Notice, the space between two objects in.
