Functions are things we've been indirectly using since the first module.
print( ) and input( ) are some functions that you’ve already used. And these are inbuilt functions.
print("hello world")input("enter your age")
If you want, you can even create your own function to get some desired output.
Let’s learn some in-built functions in the video mentioned below.
Examples of in-built functions
round()
- Round function in python rounds off the decimal value of a number to its nearest integer. For example: round(65.66) = 66.
- In addition, one can give an input of the specified number of decimals to which the number should be rounded. For example, round(65.66, 1) = 65.7.
- Its syntax is:
round(number, ndigits)- number - the number to be rounded.
- ndigits - number of decimal places up to which the given number is rounded; defaults to 0.
