Write a program to create an output file, \"mydata.txt\", and write the numbers

Question

Write a program to create an output file, "mydata.txt", and
write the numbers 1 to 1000. Put 10 numbers on each line.
Format the output so that the columns line up perfectly.

1     2    3     4   5     6   7     8   9   10
11   12   13   14  15   16   17   18  19   20

Hint1:
Convert the number to a string and get its length. Then, print
the correct number of spaces before printing the number.

Hint2:
When checking the format, you will need to display the
numbers in a fixed-width font, like Courier, like below.

Hint3:
First, display the first 20 numbers on the console. Afterit's working,
print the numbers into the file.

Write a program to open "mydata.txt", read and sum up allnumbers
in the file. Print the sum on the console.
