Some whole numbers can be split into smaller pieces, where each piece contains the same number of digits. For a subset of the whole numbers which can be split evenly, the pieces are in numerically increasing order.

Examples:

• 154152 can be split evenly into two-digit pieces (15, 41, 52) increasing order
• 154152 can be split evenly into three-digit pieces (154, 152) not increasing order
• 154152 cannot be split evenly into five-digit pieces
• 173 can be split evenly into one-digit pieces (1, 7, 3) not increasing order
• 173 can be split evenly into three-digit pieces (173) increasing order
• 173 cannot be split evenly into two-digit pieces

Design, implement and test a Python program that checks to see if a user-supplied whole number can be split evenly into pieces that are in numerically increasing order.

1. The program will prompt the user to enter a whole number. If the user enters an invalid input (anything other than a whole number), the program will repeatedly prompt the user until a valid input is entered.
2. The program will then prompt the user to enter the number of digits in each piece. The program will verify that the input is valid (a whole number which is a proper divisor of the number of digits in the first input); if the input is invalid, the program will repeatedly prompt the user until a valid input is entered.
3. The program will split the number into pieces and display those pieces on one line (separated by commas).

The program will report whether or not the pieces are in numerically increasing order. If there is only one piece, it is defined to be in numerically increasing order.

Assignment Deliverables

The deliverable for this assignment is the source code for your Python program.

Assignment Notes

• You may not use any collection (such as a list, tuple, or dictionary) in your program.
• Be sure to prompt the user for the two inputs in the correct order. Also, your program cannot prompt the user for any other inputs.
• To grade your program, your TA will enter a series of inputs.
• You may find it easier to process the large whole number as a string when you split it into pieces.
• Leading zeroes should be ignored. 0 is not valid input.

How to approach it :

figure out how many substrings you want loop that number of times  use slices to create the substrings

• You can use the isdigit() string method to determine if a string contains only digits. Type help(str.isdigit) in the Python shell for more information.
• You can use the len() function to determine the length of a string. Type help(len) in the Python shell for more information.
• Getting the commas right in the output is surprisingly tricky because you only want commas between numbers, so leave that until everything else is working correctly.
• Leave error checking of the input until last. Begin by building your program assuming perfect input. However, plan on quite a bit of time to get the input checking details right.
