Python or Keyword

The Python or keyword is one of the logical operator. This keyword results in True, If either of the condition is True. It is a case-sensitive. It is must be used between two conditions.

The or keyword can be used in conditional statements, loops, functions to check whether the condition is True or False. It cannot be used directly between two numeric values because it will consider both the values as a True values.

Here, is the representation of Python or keyword −

condition1 or condition2

condition1 and condition2 are any numeric conditions.

Let us consider A and B be the conditions, If any one of the condition, either A or B is True, it will result in True. When A and B are False, it will result in False.

Here, is the truth-table of or keyword −

Example

Here, is an basic example of Python or keyword −

condition1=True
condition2=True
result_1=condition1 or condition2
print("The Result Of ",condition1,"or",condition2,":",result_1)
condition3=1
condition4=0
result_2=condition3 or condition4
print("The Result Of ",condition3,"or",condition4,":",result_2)

Output

Following is the output of the above code −

The Result Of  True or False : True
The Result Of  False or False : False

or keyword in if-else statements

The or keyword can be used in if-else block to check whether the given condition result in True or not. If one of the given conditions result in True than the if block is executed, otherwise else block is executed −

Example

Lets try to understand the usage of or keyword in if-else with following example −

var1=89
var2=39
var3=9
if var1 > var2 or var1 < var3:
    print("One Of the Condition is True")
else:
    print("Both The Conditions Are False")

Output

Following is the output of the above code −

One Of the Condition is True

or keyword in loops

The or keyword is also used in the loops to check the given conditions. If the given condition result in True then the loop will be executed.

Example

In the following example, we are using the or keyword in a while loop −

tuple1=[]
var1=1
while var1<30 or var1<0:
    if var1%2!=0:
        tuple1.append(var1)
    var1=var1+1   
print("We have appended the tuple1 with the odd numbers below 30 :", tuple1)

Output

Following is the output of the above code −

We have appended the tuple1 with the odd numbers below 30 : [1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29]

Python and Keyword in Functions

The or keyword is also used in function. If the given condition is satisfied then it returns True else returns False −

Example

Here, is an example of usage of or keyword in function −

def num(x,y):
    if x>y or x%y==0:
        return True
    else:
        return False
var1=204
var2=2
result_1=num(var1,var2)
print(var1,"is divisible by",var2,"True/False :",result_1)
var3=9
var4=600
result_2=num(var3,var4)
print(var3,"is divisible by",var4,"True/False :",result_2)

Output

Following is the output of the above code −

204 is divisible by 2 True/False : True
9 is divisible by 600 True/False : False

or Keyword in Numeric Value

In Python, Between two numeric values or keyword cannot be used. It will consider both the numeric values as True and result in first numeric value. If the first numeric value is 0 than results in second numeric value. If both the numeric values are zero than it will result in zero.

Example

Here, is an example for usage of or keyword between numeric values −

var1=34
var2=67
result_1= var1 or var2
print("The Result of Two numeric values",var1,"or",var2,":",result_1)
var3=0
var4=18
result_2= var3 or var4
print("The Result of Two numeric values",var3,"or",var4,":",result_2)
var5=0
var6=0
result_3= var5 or var6
print("The Result of Two numeric values",var5,"or",var6,":",result_3)

Output

Following is the output of the above code −

The Result of Two numeric values 34 or 67 : 34
The Result of Two numeric values 0 or 18 : 18
The Result of Two numeric values 0 or 0 : 0
