This article discusses methods to assign values to variables.
Method 1: Direct Initialisation Method
In this method, you will directly assign the value in python but in other programming languages like C, and C++, you have to first initialize the data type of the variable. So, In Python, there is no need for explicit declaration in variables as compared to using some other programming languages. You can start using the variable right away.
C++
// C++ code to demonstrate variable assignment// upon condition using Direct Initialisation Method#include <bits/stdc++.h>using namespace std;int main(){ // initialising variables directly int a = 5; // printing value of a cout << "The value of a is: " << a;} |
C
// C code to demonstrate variable assignment// upon condition using Direct Initialisation Method#include <stdio.h>int main(){ // initialising variables directly int a = 5; // printing value of a printf("The value of a is: %d", a);} |
Java
// Java code to demonstrate variable assignment// upon condition using Direct Initialisation Methodimport java.io.*;class GFG { public static void main(String args[]) { // initialising variables directly int a = 5; // printing value of a System.out.println("The value of a is: " + a); }} |
Python3
# Python 3 code to demonstrate variable assignment# upon condition using Direct Initialisation Method# initialising variable directlya = 5# printing value of aprint ("The value of a is: " + str(a)) |
C#
// C# code to demonstrate variable assignment// upon condition using Direct Initialisation Methodusing System; class GFG{ public static void Main(String []args){ // Initialising variables directly int a = 5; // Printing value of a Console.Write("The value of a is: " + a);}} // This code is contributed by shivanisinghss2110 |
Javascript
<script>// JavaScript code to demonstrate variable assignment// upon condition using Direct Initialisation Method // initialising variables directly var a = 5; // printing value of a document.write("The value of a is: " + a);</script>// this code is contributed by shivanisinghss2110 |
Output
The value of a is: 5
Assigning multiple values to different variables :
Unlike other languages, we can easily assign values to multiple variables in python easily.
Java
/*package whatever //do not write package name here *///Assigning multiple values in javaimport java.io.*;class GFG { public static void main (String[] args) { String a="Lazyroar",b="for",c="Lazyroar"; System.out.println(a+b+c); }} |
Python
# Assigning multiple values in single linea,b,c="Lazyroar","for","Lazyroar"print(a+b+c) |
Javascript
# Assigning multiple values in single linelet [a,b,c]=["Lazyroar","for","Lazyroar"]console.log(a+b+c); |
Output
neveropen
Method 2: Using Conditional Operator (?:)
This method is also called Ternary operators. So Basic Syntax of a Conditional Operator is:-
condition? True_value : False_Value
Using Conditional Operator, you can write one line code in python. The conditional operator works in such a way that first evaluates the condition, if the condition is true, the first expression( True_value) will print else evaluates the second expression(False_Value).
Below is the syntax in other popular languages.
C++
// C++ code to demonstrate variable assignment// upon condition using Conditional Operator#include <bits/stdc++.h>using namespace std;int main(){ // initialising variables using Conditional Operator int a = 20 > 10 ? 1 : 0; // printing value of a cout << "The value of a is: " << a;} |
C
// C code to demonstrate variable assignment// upon condition using Conditional Operator#include <stdio.h>int main(){ // initialising variables using Conditional Operator int a = 20 > 10 ? 1 : 0; // printing value of a printf("The value of a is: %d", a);} |
Java
// Java code to demonstrate variable assignment// upon condition using Conditional Operatorimport java.io.*;class GFG { public static void main(String args[]) { // initialising variables using Conditional Operator int a = 20 > 10 ? 1 : 0; // printing value of a System.out.println("The value of a is: " + a); }} |
Python3
# Python3 code to demonstrate variable assignment# upon condition using Conditional Operator# Initialising variables using Conditional Operatora = 1 if 20 > 10 else 0# Printing value of aprint("The value of a is: " , str(a))# This code is contributed by shivanisinghss2110 |
C#
// C# code to demonstrate variable assignment// upon condition using Conditional Operatorusing System;class GFG { public static void Main(String []args) { // initialising variables using Conditional Operator int a = 20 > 10 ? 1 : 0; // printing value of a Console.Write("The value of a is: " + a); }}// this code is contributed by shivanisinghss2110 |
Javascript
<script>// JavaScript code to demonstrate variable assignment// upon condition using Conditional Operator // initialising variables using Conditional Operator var a = 20 > 10 ? 1 : 0; // printing value of a document.write("The value of a is: " + a);// This code is contributed by shivanisinghss2110</script> |
Output
The value of a is: 1
One liner if-else instead of Conditional Operator (?:) in Python
Python3
# Python 3 code to demonstrate variable assignment# upon condition using One liner if-else# initialising variable using Conditional Operator# a = 20 > 10 ? 1 : 0 is not possible in Python# Instead there is one liner if-elsea = 1 if 20 > 10 else 0# printing value of aprint ("The value of a is: " + str(a)) |
Output
The value of a is: 1
