Usingtime.sleep()inside a loop can lead to inefficient code, especially when the sleep duration is significant. This is becausetime.sleep()blocks the execution of the entire thread, including other iterations of the loop. To optimize the use oftime.sleep()inside loops, consider the following ...
In addition, in Python the definition line of an if/else/elif statement, a for or while loop, a function, or a class is ended by a colon. In MATLAB, the colon is not used to end the line. Consider this code example: Python 1num = 10 2 3if num == 10: 4 print("num is eq...

Let’s pause for a moment and review what we know (so far) about Python functions. Bullet Points Functions are named chunks of code. Thedefkeyword is used to name a function, with the function’s code indented under (and relative to) thedefkeyword. ...
