如何在打印语句中进行循环

Question

I am trying to format my output to print with 7 whitespaces at the beginning.

for i in range(1,17):
    print(i, end=' ')

How could I include that in a formatted statement? For example:

print("{0:>7}".format(for loop to print horizontal line of numbers)

If you want exactly 7 spaces (not a total width of 7 characters, including the value), you probably want to manually add " " or " " * 7 . How about:

print(" "*7 + " ".join(str(i) for i in range(1, 17)))

Output:

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

If you need special formatting for the individual numbers (such as padding them to a common width), just make a format call instead of str :

print(" "*7 + " ".join(format(i, "2d") for i in range(1, 17)))

Output:

        1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16
#      ^  ^  ^  ^  ^  ^  ^  ^  ^ note extra spaces padding the 1-digit numbers to width 2
