Syntax of Loop with Counter

The syntax of a loop with a counter in Python can take different forms depending on the type of loop being used. Here are the common ways to write a loop with a counter:

1. For Loop with Range: - The syntax for a for loop with a counter using the range function is: ``` for i in range(n): # CommandA ```

- This loop will iterate over the sequence of numbers from 0 to n-1, where `i` is the loop variable that takes each value in the specified range.

2. For Loop without Range: - The syntax for a for loop with a counter without using the range function is: ``` for i in iterable: # CommandB ```

- In this case, the loop iterates over the elements of the specified iterable, and `i` takes each value in the iterable.

3. While Loop with Range: - The syntax for a while loop with a counter using the range function is not a standard construct in Python. While loops typically use a condition to control the iteration, and the range function is not directly used within a while loop.

4. While Loop without Range: - The syntax for a while loop with a counter without using the range function is: ``` while condition: # CommandG ```

- In this case, the loop continues to execute as long as the specified condition is true.

5. If...Else Statement: - The if...else statement is used to perform different actions based on whether a certain condition is true or false. The syntax is: ``` if condition: # CommandC else: # CommandD ```

- Here, if the condition is true, CommandC is executed; otherwise, CommandD is executed.

These are the basic syntax forms for loops with counters and if...else statements in Python. Each form serves a specific purpose and can be used in different scenarios based on the requirements of the program.
