Simple Small Multiplication table program in Python-CodePudding

rows = int(input("Enter number: "))

print('1\t2\t3')
print('********************')
for i in range(1,rows 1):
    print(i*1,end='')
    print('\t',i*2,end='')
    print('\t',i*3)

Usually end="" makes not jumping in a new line. But with under print('\t',i*2,end=''). Everything is in vertical line . And I want it to be this way . But i dont get it if end="" makes it al horizonal why is it vertical?

CodePudding user response：

Consider using f-strings to align the columns dynamically:

num_rows = int(input('Enter number: '))
num_cols = 3
align = '<'
col_gap = 1
col_width = len(str(num_rows * num_cols))   col_gap
print(''.join(f'{c:{align}{col_width}}' for c in range(1, num_cols 1)))
print('*' * (col_width * num_cols - col_gap))
for r in range(1, num_rows 1):
    print(''.join(f'{r*c:{align}{col_width}}' for c in range(1, num_cols 1)))
