What are some basic examples of conditional statements in Python?

In Python, conditional statements allow you to execute certain code based on whether a condition is true or false. For example:

1. if statement:

   x = 10
   if x > 5:
       print('x is greater than 5')
   

2. if-else statement:

   x = 3
   if x > 5:
       print('x is greater than 5')
   else:
       print('x is not greater than 5')
   

3. if-elif-else statement:

   x = 5
   if x < 5:
       print('x is less than 5')
   elif x == 5:
       print('x is equal to 5')
   else:
       print('x is greater than 5')
   

These examples demonstrate how to control the flow of your program based on conditions.

Can you explain the if-elif-else statement in more detail?

Sure! The if-elif-else statement allows you to check multiple conditions in sequence. Here's how it works:

• The if statement checks the first condition. If it's true, the code block under it executes.
• If the first condition is false, the elif (short for 'else if') checks the next condition. You can have multiple elif statements.
• If none of the conditions are true, the else block executes.

Here's an example:

x = 20
if x < 10:
    print('x is less than 10')
elif x < 20:
    print('x is less than 20')
else:
    print('x is 20 or more')

In this case, the output will be 'x is 20 or more' because the first two conditions are false.

What happens if I don't include an else statement?

If you don't include an else statement, the program will simply skip the block of code that follows the if and elif statements if none of the conditions are met. It won't throw an error; it just means that nothing will happen if all conditions are false. Here's an example:

x = 5
if x > 10:
    print('x is greater than 10')
elif x > 7:
    print('x is greater than 7')
# No else statement here

In this case, since both conditions are false, nothing will be printed.
