### Python examples of or operator

Example1: Take two numbers and test the conditions using or operator

# python code to demonstrate example of
# or  keyword/operator

a = 10
b = 20

# printing return values
print(a>=10 or b>=20)
print(a>10 or b>20)
print(a==10 or b==20)
print(a==10 or b!=20)

Output

True
False
True
True

Example 2: Input a number and check whether it is divisible by 2 or 3

# Input a number and check whether
# it is divisible by 2 or 3

# input
num = int(input("Enter a number: "))

# checking num is divisible by 2 or 3
if num%2==0 or num%3==0:
print("Yes, ", num, " is divisble by 2 or 3")
else:
print("No, ", num, " is not divisble by 2 or 3")

Output

First run:
Enter a number: 66
Yes,  66  is divisble by 2 or 3

Second run:
Enter a number: 5
No,  5  is not divisble by 2 or 3

Example 3: Input a string and check whether it is "Hello" or "World"

# Input a string and check
# whether it is "Hello" or "World"

# input
string = input("Enter a string: ")

# checking the conditions
if string=="Hello" or string=="World":
print("Yes, \"", string, "\" is either \"Hello\" or \"World\"")
else:
print("No, \"", string, "\" is neither \"Hello\" nor \"World\"")

Output

First run:
Enter a string: Hello
Yes, " Hello " is either "Hello" or "World"

Second run:
Enter a string: World
Yes, " World " is either "Hello" or "World"

Third run:
Enter a string: IncludeHelp
No, " IncludeHelp " is neither "Hello" nor "World"
