## Overview


In this shot, we will illustrate to generate a C shape using a nested loop in Python. A **nested loop** means a loop added into another loop. 

Let's consider we want to return an output with a shape of 'C' like the one shown below:

```python3
xxxxxxx
xx
xx
xx
xxxxxxxx
```

We will create a C-shape using the `for` loop in Python:

## Code

numbers =[7, 2, 2, 2, 7]
for x_item in numbers:
    print('x' * x_item)


## Explanation

* **Line 1**: We create a list of numbers.
* **Line 2**: We create a `for` loop to iterate over each item in the list using a variable `x_item`.
* **Line 3**: We print the output: each item in the list starting with the first item `7` multiplied by `x`. This means we have seven `x`'s on the first line. On the second line, we have two `x`'s, which continue till the last item of the list.

In Python, it’s a straightforward way to create a C shape. However, this is a cheat.

> **FYI**: Python allows the multiplication of a number to a string to repeat the string. A lot of other programming languages do not support this feature. 
	
## Using a nested loop

Now, we will create a C-shape using a nested loop:
### Code

numbers =[7, 2, 2, 2, 7]
for x_item in numbers:
    output=''
    for count in range(x_item):
        output += 'x'
    print(output)


### Explanation

* **Line 1**: We create a list of numbers 
* **Line 2**: We create a `for` loop to iterate over each item in the list using a variable `x_item`.
* **Line 3**: We define a variable `output` and initially set it as an empty string.
* **Line 4**: We create an inner loop using the `range` function to generate a sequence of numbers starting from `0` to `x_item`. So in the first iteration, `x_item` is `7`, the range of `7` will generate the numbers `0`, `1`, `2`, `3`, `4`, `5`, and `6`. This inner loop will execute seven times,  representing the `x_item`.
* **Lines 4 and 5**: We append an `x` to our `output` variable.
* **Line 6**: We print the output.

For the first iteration, we print our `7` `x`’s on the first row, then for the second iteration of our outer loop in **line 2**, here `x_item` is `2`. 

In **line 3**, since we set the `output` variable to an empty string,  Python goes over to our inner loop to append `2` `x`’s (the value of `x_item` is `2`) to the `output` variable and then print.
