for loop
A "for loop" in Python is a control flow statement that allows you to iterate over a sequence or an iterable object (such as a list, tuple, string, or range) and execute a block of code for each item in the sequence. Here's a definition and common uses of the for loop:

• Iterating Over Lists and Sequences: We can use a for loop to iterate over the elements of a list, tuple, or other sequence types.
• Looping Through Strings: Strings are sequences of characters, and we can use a for loop to iterate through each character in a string.
• Iterating Over Ranges: Ranges are often used with for loops when you need to generate a sequence of numbers.
• Working with Iterators and Generators: Python supports custom iterators and generators, which can be used with for loops to create custom sequences.
• Processing Data Structures: for loops are commonly used for processing data structures, like dictionaries and sets.

The syntax and the flowchart of a for loop:

for loops are essential for iterating over various types of data, and they provide a convenient way to perform repetitive tasks and process collections of data in Python programs. They are a fundamental building block of many Python programs and are widely used in everyday coding tasks.

# for loop

'''
syntax: 
    for loop_var in sequence:
        statement block
'''

# Example 1 - using range()
# for i in range(0, 11):
#     print(i, end=" ")

n = 100
# for i in range(1, n+1):
#     print(i, end=" ")

# for i in range(1, n+1):
#     print(i, end=" ")

# Example 2
# for i in range(n):
#     print(i, end=" ")

# Example 3 - sum and average
# sumN = 0
# user_input = int(input("Enter a number: "))
# avg = 0.0
# for i in range(1, user_input+1):
#     sumN = sumN + i
# avg = sumN / i
# print(f'The sum of fist {user_input} is', sumN)
# print(f'The average is', avg)

Q1. Write a program to print the multiplication table of n, where n is the user input
Q2. Write a program to check if a given number is prime or composite number
