In the above example, we have created a function namedgreet(). Here's how the control of the program flows: Working of Python Function Here, When the functiongreet()is called, the program's control transfers to the function definition. All the code inside the function is executed. The con...
In the above example, the program first checks the very first if statement. Since it turns out to be false, the body of the if statement is not executed, and the program goes to the next elif statement. It also turns out to be false and again the body of the elif block is skipped...
This allows your program to overlap the waiting times and get the final result faster. Yippee! That was the goal. Are there any problems with the multi-threaded version? Well, as you can see from the example, it takes a little more code to make this happen, and you really have to ...
Example: input command input command is used to take input from the user. The flow of the program will be stopped until the user has entered any value. Whatever the user enters it will be converted into a string by the input function. If you want to take an integer as input then you...
