A simple Python if statement test just one condition. An else statement contains a block of code that executes if the conditional expression in the if statement resolves to 0 or a FALSE value. Other decision-making statements in Python are the following: If Statement: It is used to analyze if the condition at hand is true or false. so the first condition is not true, also the elif condition is not true, An if else Python statement evaluates whether an expression is true or false.

In this example we use two variables, a and b, The general syntax of single if and else statement in Python is: Lately I like atom + script plugin a lot because of the minimalist appearance, it helps me to focus on the code and has a good UI. If we want to evaluate more complex scenarios, our code has to test multiple conditions together. In the following examples, we will see how we can use python or logical operator to form a compound logical expression. Amit Arora Amit Arora Python Programming Language Tutorial Python Tutorial Programming Tutorial The decision-making process is required when we want to execute code only if a specific condition is satisfied.
