When there are multiple conditions to check, you can use the elif clause (short for "else if"). Python evaluates each condition one by one until it finds one that is True. If none are True, the else block is executed. Syntax: if expression1 : statement_1 statement_2 ... elif expres...

Q. How do I use the if-elif-else statement in a bash script to handle multiple conditions? Theif-elif-elsestatement in Bash allows you to handle multiple conditions sequentially, as in the example below. if [ condition1 ]; then
Dans l'exemple ci-dessous, vous définissez deux variablesroometarea. Vous construisez ensuite les conditionsif-elif-elseetif-elsepourroometarea, respectivement. Dans la première condition, vous vérifiezifque vous regardez dans la cuisine,elifque vous regardez dans la chambre,elseque vous reg...
Python also supports nested conditional logic, meaning that you can nestif,elif, andelsestatements to create even more complex programs. To nest conditions, indent the inner conditions, and everything at the same level of indentation will be run in the same code block: ...
Python will evalute the if condition and if it evaluates to False then it will evalute the elif blocks and execute the elif block whose expression evaluates to True. If multiple elif conditions become True, then the first elif block will be executed. The following example demonstrates if, ...
Python if else语句 (Python if else Statement) The if-else condition is useful when you have multiple conditions to be evaluated in a program. Suppose you want to check for a particular condition and if that evaluates to false, you can then opt for another condition checking to evaluate it....
In our life we often encounters situation where we need to take decisions from among multiple conditions. In programming also, we can perform such multiple decision-making code using if-elif statements. In this chapter, we will learn about the elif statement in Python. Also, we will see how...
Let's say you are given a time and you have to tell what phase of the day it is- (morning, noon, afternoon, evening or night). You will have to check the given time against multiple ranges of time within which each of the 5 phases lies. Therefore, the following conditions: ...
We can also use nested if statements. This can be useful if you want to checkmultiple conditions. Consider the code below: We see both print messages. The first if statement matches, which is why it prints the first message and runs the second if statement. The second if statement also ...
