The “if” statement is primarily used to control our program’s direction. It is used to skip the execution of specific results we don’t intend to execute. The basic structure of an “if” statement in python is typing the word “if” (lower case) followed by the condition with a co...
We have a string, "Hello World", which we want to reverse: The String to Reverse txt ="Hello World"[::-1] print(txt) Create a slice that starts at the end of the string, and moves backwards. In this particular example, the slice statement[::-1]means start at the end of the st...
If/then/elif –This is the most common kind of conditional statement in Python. The compiler uses the if statement to check if something is true or false in code and then only executes another block if it is true. For example: if 1 == 1: print('Yes') if 2 == 2: print('No')...
If the while loop isn't designed to end with a certain condition by itself, we can force an exit with a break statement. This break statement makes a while loop terminate. The loop then ends and the program continues with whatever code is left in the program after the while loop. ...
The pass statement does nothing in Python, which is helpful for using as a placeholder in if statement branches, functions, and classes. In layman's terms, pass tells Python to skip this line and do nothing. To demonstrate how pass works, let's write a small script to iterate through the...

In Python, thebreakstatement allows you to exit out of a loop when an external condition is triggered. You’ll put thebreakstatement within the code block under your loop statement, usually after a conditionalifstatement. Info:To follow along with the example code in this tutorial, open a Py...
