从文本文件的Python字典

Question

Hello I have a file text that holds a sequence like this:

TCA:DateIn,TimeIn,Content,Quantity,Company,TankerName,Country,PortFrom  
26/02/2013,15:00,Natural gas,30000,Linkers, Blue Ice, China,Shanghai
09/03/2013,06:30,Sugar,45000,Navigators,Lady Fish, Netherlands, Rotterdam 

how can I using dictionary, header name as keys(DateIn,TimeIn...) and the lines below the values display it into something like this, with the columns being separated by tabs rather than by commas:

TCA:TankerName Company      Country     DateIn        TimeIn     PortFrom     Content      Quantity
Blue Ice       Linkers      China       26/02/2013    15:00      Shanghai     NaturalGas   30000
Lady Fish      Navigators   Netherlands 09/03/2013    06:30      Rotterdam    Sugar        45000

I have tried many thing but that I can't problem is that I am not able to relate key with values. I am currently using python 3.3.1 but if it works using another version no problem

Thanks

Have a look at the Python CSV module:

This will get you started:

import csv

with open('/tmp/ships.csv','r') as din:
    scsv=csv.reader(din)
    for i,row in enumerate(scsv):
        if i:
            for type,data in zip(header,row):
                d[type].append(data.strip())
        else:
            header=row
            d={item:[] for item in row}

print(d)
