Python Pyramid Pattern with Numbers

This Python code prints an upward number pyramid pattern. The variable n controls the height of the pyramid.

It uses nested loops to print spaces and numbers for each row. The outer loop iterates over each row, the first inner loop prints spaces (n-i-1), and the second inner loop prints numbers from 1 to (2*i+1).

To customize the height, change the value of n. The output for n=5 is:

    1
   123
  12345
 1234567
123456789

This pattern is a classic exercise for practicing loops in Python.
