Write a short program that uses a for loop to write the numbers 1 through 10 to a file.

Short answer

Question: Write a short program that uses a for loop to write the numbers 1 through 10 to a file. Answer: ```python for i in range(1, 11): with open('numbers.txt', 'w') as file: file.write(str(i) + '\n') ```

Step-by-step solution

1. Initialize the for loop

To iterate through the numbers 1 through 10, we will use a for loop with a range function: `for i in range(1, 11):`.

2. Open a file for writing

We will need to open a file to write the numbers. Use the `with open()` function, and provide the filename and write mode: `with open('numbers.txt', 'w') as file:`.

3. Write the numbers to the file

Inside the for loop and the opened file block, write the numbers to the file using `file.write()`. We will also convert the numbers to strings with the `str()` function, as they need to be in a string format to be written to a file: `file.write(str(i) + '\n')`.

4. Close the file

Once we have written all the numbers to the file, the 'with open()' block will automatically close the file after it's done with its operations. Here is the complete code for solving the problem: ``` # 1. Initialize the for loop for i in range(1, 11): # 2. Open a file for writing with open('numbers.txt', 'w') as file: # 3. Write the numbers to the file file.write(str(i) + '\n') # 4. Close the file (handled automatically) ```
