changing .format length in python 3

Question

I want to change the length of the formatting in my code,

symbolWanted = input('Input symbol wanted for triangle: ')
baseLength = int(input('Input base length of triangle(odd number): '))
for i in range (1,baseLength,2):
   print(('{:^100}').format(i*symbolWanted))

is there a way to change the length of the format using a variable e.g.

print(('{:^baseLength}').format(i*symbolWanted))

Thank you.

Answer 1

You can use variables in format strings:

print(('{:^{bl}}').format(i*symbolWanted, bl=baseLength))
