Conditional statements are a fundamental part of programming, allowing code to make decisions based on certain conditions. In Python, theif/else statementhelps control the execution flow by running different blocks of code depending on whether a condition is met or not. This Basic Syntax ifcondition...

After a given condition, we can use multiple statements in python. If the condition is true, the following statement or operation is executed, or if there are alternate statements or operations mentioned to execute. If the condition is false, that statement is executed. If no alternate statement...
Logical operators are used in Python to combine multiple expressions into single-line expressions. In Python, logical operators such as OR, AND, and NOT return the Boolean value “True or False”. These operators help us to combine multiple decisions-driven statements. Logical operators are used ...

So far, we have presented a Boolean option for conditional statements, with eachifstatement evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif...
We can easily implement switch-case statements logic using theif-else-elif statements. However, we can implement switch-case like behavior in Python using custom code. Implementing Switch-Case in Python There are two ways to implement switch-case behavior in Python. ...
In Python, punctuations likecolon (:)are mandatory in some places, likeif condition, looping statements, defining functions, etc.If you forget to include the expected punctuation in the code, it will throw a syntax error. Although this cause of the error may look very simple, sometimes it ca...
