If you search for something, a good entry to the Library Reference is its index (linked at the top-right corner of the Library Reference page). Be sure to have the Library Reference bookmarked since you will use it more often. Alternatively, Python Documentation is also available at.

A list of all operators is given in the Python Documentation, Library Reference (on MS Windows it should be in your Python menu). It should actually not be used on =.Īs a final exercise with comparison operators, try out some others. This exercise learns you to be careful to use = on floating points, since you can never be sure about the outcome when the values which are compared are almost equal. This is caused by the (un-)precision how floating-points are stored in the computer. You will notice that Python considers 12.0 and 12.000000000000000001 as equal values.

Does it return the value for xIsEqualToY that you expected? Hope you like the article.As you know this has changed the type of x and y to floating point.

I am very enthusiastic about programming and its real applications including software development, machine learning, and data science. About The Author Prashant SharmaĬurrently, I Am pursuing my Bachelors of Technology( B.Tech) from Vellore Institute of Technology. Learning Python or another programming language begins with understanding the fundamental concepts that form its foundation.īy the end of this text, you should understand the various If else conditions used in python.

If you’re reading this, you’re most likely learning Python or trying to become a Python developer.

Nested if statements can be used to nest one If condition inside another.

By declaring all of the conditions in a single statement, we can reduce the number of codes that must be executed.

In a program, any number of Elif conditions can be used.

When there is a third possible outcome, the Elif statement is used.

When one of the conditions is false, the If-else condition is used to print the statement.

The If the condition is used to print the result when only one of the conditions listed is true or false.

Print('A is greater') if a > b else print('=') if a = b else print('B is greater') #single line if-else statement, with 3 conditions a = 3 In simple words, If you have only one statement to execute, one for if, and one for else, you can put it all on the same line. It is used to mention If-else statements in one line in which there is only one statement to execute in both if and else blocks. The output of the program : “i is greater than 11.” The Short Hand if statement in Python has the following syntax: if condition: statement This statement can be mentioned in the same line which holds the If statement. Short Hand if statement is used when only one statement needs to be executed inside the if block. The Nested if statement in Python has the following syntax: if (condition1): In Nested If statements, the indentation (whitespace at the beginning) to determine the scope of each statement should take precedence. If, If-else, and If…elif…else statements can be used in the program. This is used when a variable must be processed more than once.

num = 7Ī Nested IF statement is one in which an If statement is nestled inside another If statement. We will check if the number is positive, negative, or zero. The If…Elif.else statement in Python has the subsequent syntax: if condition : If it is false, the Elif statement will be executed if it also comes false, the Else statement will be executed. In this case, the If condition is evaluated first. #Will executes this block if the condition is falseĮxample for better understanding: num = 5

#Will executes this block if the condition is true The if…Else statement in Python has the following syntax: if condition : When the condition is true, the statement inside the if block is executed if the condition is false, the statement outside the if block is executed. This statement is used when both the true and false parts of a given condition are specified to be executed.
