Python And Keyword

The and keyword in Python is a logical operator used to combine two conditions. It returns True if both conditions are true, otherwise, it returns False. It is commonly used in if statements, loops and Boolean expressions.

Let's understand with a simple example.

x = 10
y = 5

if x > 0 and y > 0:
    print("Both conditions are true")
    
if x < 0 and y > 0:
    print("One condition is false")
    
if x < 0 and y < 0:
    print("Both conditions are false")    

Both conditions are true

Explanation: Only the first if statement is evaluated as True because both the conditions in it are true.

Now, let's explore some common use cases of "and" keyword with examples.

Using and in Conditional Statements

and keyword is mostly used in if statements to check multiple conditions at once.

age = 20
inc = 5000

if age > 18 and inc > 3000:
    print("Eligible for a credit card")

Eligible for a credit card

Using and in Loops

and keyword can be used inside loops to control iteration based on multiple conditions.

a = 1

while a < 10 and a % 2 != 0:
    print(a)
    a += 2

1
3
5
7
9

Explanation: in the code we are printing all odd numbers less than 10 by simultaneously checking for two conditions (a < 10 and a % 2 != 0) using and.

Using and with Boolean Values

a = True
b = False

print(a and b)  
print(a and True)  
print(False and False)  

False
True
False

Explanation: Only those conditions are being evaluated as True where both left and right part of the and keyword is True.
