用2位数字初始化列表

Question

I have a list of other lists I am using to represent a map of my workspace. Here is a simplified version:

areaMap = [[00,00,00,00,00],[00,00,01,11,01]]

Now, when i print this onto the screen using:

for x in range(len(areaMap)):
    print(areaMap[x])

the leading zero will be chopped off:

[0,0,0,0,0],
[0,0,1,11,1]

I need these numbers to have 2 digits so they are visually appealing when printed. I tried using:

for y in areaMap:
    [str(item).zfill(6) for item in areaMap[y]]

but this creates unneeded quotation marks and spaces.

Answer 1

You need to specify the format for the entirety of each line; for example

for x in areaMap:
    print("[%s]" % (",".join(["%02d"%z for z in x])))
