Question

I am new to Python. Have a question regarding join function.

masterlist = [
    ('ap172', ['33', '212-583-1173', '19 Boxer Rd.', 'New York', 'NY', '10005']),
    ('axe99', ['42', '212-582-5959', '315 W. 115th Street, Apt. 11B', 'New York', 'NY', '10027'])
]

I want to print each element of list delimited by pipe.

If I try:

for i in masterlist:
    mystring = '|'.join(i)                                      
    print mystring

The error is:

TypeError: sequence item 1: expected string, list found

So I am trying:

for i in masterlist:
    mystring = i[0] 
    mystring += '|'.join(i[1])                                  
    print mystring

and I get:

ap17233|212-583-1173|19 Boxer Rd.|New York|NY|10005
axe9942|212-582-5959|315 W. 115th Street, Apt. 11B|New York|NY|10027

So it works but would like to know if there is a better way to join the above masterlist using join function?

Answer 1

I think splitting up the tuples in the for loop would be cleaner.

for identifier, data in masterlist:
     print "%s%s" %(identifier, '|'.join(data))
