使用sys.stdout.write（）时如何切片

Question

I have an input like this:

country = 'CANADA'

and I want the output to be like this:

C*A*N*A*D*A

I tried to do this:

for letter in country:
    tag = letter+'*'
    sys.stdout.write(tag)

But I will get C*A*N*A*D*A* instead of C*A*N*A*D*A . So how do I slice the sys.stdout.write or do I have to do other format?

Answer 1

>>> country = 'CANADA'
>>> '*'.join(country)
'C*A*N*A*D*A'

Your version with slicing:

>>> country = 'CANADA'
>>> tag = ''
>>> for letter in country:
        tag += letter+'*'


>>> sys.stdout.write(tag[:-1]) # everything up until the last character
C*A*N*A*D*A
