Learning Goals

In this lab, you will

Use the for OBJ in CONTAINER loop to go over characters in the string
Use if statements to compare the strings and characters
Use if statements to detect when to output a singular noun
Create and increment variables to count (use the accumulator pattern)
Use string concatenation to create a new string to assemble the requested output

Instructions

Write a program that asks the user for a line of text and counts how many spaces, periods, or commas the text contains using the specified output format.

Examples

If the input is:

Hello, world.

the output is:

There are 1 space, 1 period, and 1 comma.

If the input is:

Listen, Mr. Jones, calm down.

the output is:

There are 4 spaces, 2 periods, and 2 commas.

Hints

Review Figure 6.5.2 to see how to iterate over characters.
Go over the string, character by character, and increment the counters for the requested characters.
You will need a separate counter for every symbol that you are counting.
Do not forget - initially, we do not have any characters counted, so the counter should be 0.
You will need a separate check for each symbol to know whether to print its counter with a singular or a plural noun

**Title: LAB: Count Spaces, Periods, or Commas (Exercise 6.18.1)**

**File: main.py**

This coding exercise is designed to teach how to analyze text input in Python by counting specific characters: spaces, commas, and periods. Below is a transcription of the code framework provided in the lab activity:

```python
1 user_text = input()
2
3 num_spaces = ...
4 num_commas = ...
5 num_periods = ...
6
7 # TODO: for loop to go over each character in user_text
8
9 output = f"There are "
10 if num_spaces == 1:
11 output += f"1 space, "
12 else:
13 output += f"{num_spaces} spaces, "
14
15 # TODO: finish the concatenation of the output string
```

### Code Explanation:

1. **User Input:**
- `user_text = input()` captures text from the user.

2. **Variable Initialization:**
- `num_spaces`, `num_commas`, and `num_periods` are placeholders for counting spaces, commas, and periods, respectively.

3. **Loop Requirement:**
- A comment indicates the need for a `for loop` to iterate through each character in `user_text` to count spaces, commas, and periods.

4. **Output Construction:**
- Begins with a base string assigned to `output`.
- Conditional logic is used to check the number of spaces:
- If there is exactly one space, the string is updated accordingly.
- Otherwise, it indicates the total number of spaces.

5. **Further Steps:**
- A `TODO` comment suggests completion of the output string to include counts for commas and periods.

This exercise provides practice in handling string input and performing character-specific counts. The comments guide students through areas requiring their input for a complete solution.
