将“ for循环”更改为“ while循环”

Question

想知道如何将以下for循环更改为while循环。

虽然输出相同。

for i in range(0,20, 4):
     print(i)

Answer 1

就这么简单：

i = 0
while i < 20:
    print(i)
    i += 4

Answer 2

i = 0
while i < 20:
    print(i)
    i += 4

Answer 3

会是这样的：

i = 1
while i < 20:
  print(i)
  i += 4

Answer 4

i=0
while(i<5):
    print(4*i)
    i+=1
