我如何使用 for 循环来弄清楚如何解决这个问题？

Question

enter image description here 5

I have to use a for loop to code this. I have tried many times but it never works.

enter code here
num_of_times = 5
for x in range(1, num_of_times, 5):
 for y in range(5, i+5):
  print(y, end= '')
 print('')

Answer 1

You can try this:

lst = []

for i in range(1, 5):
    lst.append(i * 5)
    print(*lst)

Answer 2

You basically want to print multiple of 5. That could be achieved with two nested for loops:

max = 5
for i in range(max):
    line = ''
    for j in range(i+1):
        line += str(5 * (j+1)) + ' '
    print(line)

The first loop goes from 0 to max-1 and stores the index in i ; the second loop goes from 0 to i+1 and stores the index in j . Then, the result of 5 * (j+1) is added to a variable called line printed at the end of the j-loop. Feel free to follow the loops and the value of each variable at every step with a paper and a pen, that should help you.

Answer 3

Here you go

for i in range(1,6):
    for j in range (1, i+1):
        print(j*5, end = ' ')
    print('')
