if elif else¶

The if...elif...else statement is a powerful construct in Python for making conditional decisions. It allows you to execute different blocks of code based on multiple conditions.
```
if condition1:
    # Code to execute if condition1 is True
    print('inside condition 1')
elif condition2:
    # Code to execute if condition1 is False and condition2 is True
    print('inside condition 2')
else:
    # Code to execute if all conditions are False
    print('all above conditions failed. i am inside else part now 😂')
```
- Explanation
  - if condition1: The program checks if condition1 is True.
    - If condition1 is True, the indented code block below it is executed, and the rest of the elif and else blocks are skipped.
  - elif condition2 (optional): This is an "else if" clause.
    - If condition1 is False, the program then checks if condition2 is True.
    - If condition2 is True, the code block following elif is executed, and the else block is skipped.
  - else (optional): This is a catch-all block.
    - If all the preceding conditions (condition1 and any elif conditions) are False, the code block within else is executed.

from random import randint
grade = randint(70, 100)

if grade >= 90:
    print("Excellent! You got an A.")
elif grade >= 80:
    print("Great job! You got a B.")
else:
    print("Keep studying! You got a C or below.")
from random import randint
grade = randint(70, 100)

if grade >= 90:
    print("Excellent! You got an A.")
elif grade >= 80:
    print("Great job! You got a B.")
else:
    print("Keep studying! You got a C or below.")

Explanation
- The program prompts the user for their grade.
- The if statement checks if the grade is 90 or higher. If so, it prints "Excellent!".
- The elif statement checks if the grade is at least 80 but less than 90. If so, it prints "Great job!".
- The else block executes if the grade is below 80.

You can have multiple elif conditions to check for different scenarios.
The else block is optional, but it's a good practice to include it to handle cases where none of the conditions are True.
Indentation is crucial in Python. Make sure all code blocks within if, elif, and else are properly indented (usually by 4 spaces).
By mastering if...elif...else statements, you can write Python programs that make informed decisions based on various conditions, making your code more flexible and responsive.
