How to assign values to variables in Python and other languages

31 May, 2022
This article discusses methods to assign values to variables. 
In this method, you will directly assign the value in python but in other programming languages like C, C++, you have to first initialise the data type of variable. So, In Python, there is no need of explicit declaration  in variables as compare to using some other programming languages. You can start using the variable right away.
C++
C
Java
Python3
C#
Javascript
// 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 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 code to demonstrate variable assignment// upon condition using Direct Initialisation Method import 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);    }}
# 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# 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
<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
The value of a is: 5
 
This method is also called Ternary operators. So Basic Syntax of Conditional Operator is:-
                                                                         condition? True_value : False_Value
Using Conditional Operator, you can write one line code in python. The conditional operator works in a such way that first evaluates the condition, if  condition is true , first expression( True_value) will print else evaluates the second expression(False_Value).
Below is the syntax in other popular languages.
C++
C
Java
Python3
C#
Javascript
// 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 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 code to demonstrate variable assignment// upon condition using Conditional Operator import 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 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# code to demonstrate variable assignment// upon condition using Conditional Operator using 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
<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>
The value of a is: 1
 
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))
The value of a is: 1
