Python Libraries

A Library is a collection of functions and methods that can be used to reduce repetitive tasks. These functions are stored in different files to keep your code more organized and readable.

A library that comes pre-installed with Python is the time library. Here's an example of how to use a library:

import time

start_time = time.time() #gets current time

time.sleep(1) #pauses for 1 second

end_time = time.time()

total_time = end_time - start_time

print("Seconds taken:")

print(total_time)

When using a library, you use the library name and the function name with a period in between. To skip this step, you can import only specific functions like this:

from time import sleep

sleep(1)

from time import *

#the * means all functions will be imported

time()

You can change the prefix of your library call by importing the library as variable name: import RoboPiLib as RPL

If you need to import a library from another directory, you can use the relative path of your current file.

import directory/file
