将多个输入CSV文件中的数据以列格式写入单个CSV中

Question

I'm trying to

• loop over multiple csv files,

• extract information from them

• write an output into one new csv file with a row for each of the original files.

I take the information:

Name, Date, Time, Test, Navg, Percent

for each row.

I have tried to do it, however I have the problems:

1. It writes each of Name, Date, Time, Test, Navg, Percent to a NEW ROW...I want each word in a new column

2. It writes each new file to the a new row underneath(I do want it underneath, but with each word in a column.

    b = open('C:\\Users\\AClayton\\Desktop\\Data.csv', 'a') a = csv.writer(b,delimiter='\\t',lineterminator='\\n') a.writerows((Name, Date, Time, Test, Navg, Percent)) b.close() 

Note the file has been read and the data extracted in earlier code.

Answer 1

writerows interpretes the input argument as a list of rows, hence each item in your tuple is written into a separate row. Using writerow should write it into a single row.
