如何在 python 中循环步进和计数

Question

I want to be able to count 5 at every step of 2 while condition is less than 1000 for example:

i = 0
j = 2000
k = 3000
while i < 1000:
    i += 2
    for x in range(5):
        print(i)
    j += 2
    for x in range(5):
        print(j)
    k += 2
    for x in range(5):
        print(k)

but the output just print i, j, k 5 times

output:::
2
2
2
2
2
2002
2002
2002
2002
2002
3002
3002
3002
3002
3002
4

I want the the result to be: .....

2
3
4
5
6
2002
2003
2004
2005
2006
3002
3003
3004
3005
3006
8      #please note here that 8(i) continue by 2 steps from 6
9
10
etc..........

i will like to know a more simpler and pythonic way to do this. Thanks

Answer 1

That's a weird thing you're trying to do, but here is my modified version with your desired output:

a, b, c = 0, 2000, 3000
for i in range(2, 1000, 6):
    for x in range(5):
        print(a+i+x)
    for x in range(5):
        print(b+i+x)
    for x in range(5):
        print(c+i+x)

Answer 2

So you're trying to get number progression, here's one way to do it:

progression = [a for a in range(2,7)] \
            + [b for b in range(2002,2007)] \
            + [c for c in range(3002,3007)]
for i in range(0, 1000, 6):
    for p in progression:
        print(p + i)

Answer 3

You can do this in other ways but here is solution for your approach

i = 0
j = 2000
k = 3000
while i < 1000:
    i += 2
    for x in range(5):
        print(i)
        if x < 4:
            i += 1

    j += 2
    for x in range(5):
        print(j)
        if x < 4:
            j += 1

    k += 2
    for x in range(5):
        print(k)
        if x < 4:
            k += 1

Answer 4

I don't really undestand what you want to do but this output what you want:

i = 0
j = 2000
k = 3000
while i < 1000:
    i += 2
    for x in range(5):
        print(i+x)
    j += 2
    for x in range(5):
        print(j+x)
    k += 2
    for x in range(5):
        print(k+x)
    i += 4
