Python read/write CSV file

Python comes with a CSV module, and if you want to know more about it, you can refer to the official documentation

First, read operation

I do not know why, if you open the file without using the ' B ' mode, there will be interlaced, so in Windows want to normal operation of the CSV file, plus b mode. Delimiter to specify the delimiter between the various fields of reader.

def readdata (): With    open ('csvfile.csv','rb'  as fobj:         = Csv.reader (fobj,delimiter='-');         = Next (csvfilereader);        Print header        for in  csvfilereader:            print row;

Second, write operation

Header = ["name","Sex","Age"]; Datas= [("Li Fei","male", the),             ("Zhang Shan","male", -)]; With open ('Csvfile.csv','WB') asFobj:csvfilewriter= Csv.writer (fobj,delimiter='-');        Csvfilewriter.writerow (header); Csvfilewriter.writerows (datas);

These are simple CSV file read and write operations, for more detailed documentation, please refer to the official documentation
