在python中写入csv文件

Question

with open("classA.csv" , "a", newline = "") as fp:
     a = csv.writer(fp, delimiter = ",")
     data = [("{0} has scored: {1} / 10\n ".format(name,score))]
     a.writerows(data) 

I am trying to create a maths quiz that calculates the final result and then writes this result to an excel file. This is my code so far but when I look into excel, I see that the entire statement in data is stretched out across the row and would like this:

| B | o | b | h | a | s | s | c | o | r | e | d | : | 9 | / | 1 | 0

How would I be able to print out like this:

| Bob has scored: | 9/10 |

Thanks for any help!

Answer 1

You need to provide a tuple of columns in the list that you pass to writerows .

Each element in the tuple will be a column in the resulting file, and all the tuples in the list represent the rows.

For example, if you want to output:

Bob,2
Joe,3
Bill,5

Then you need to create a list like this:

[('Bob', 2), ('Joe', 3), ('Bill', 5)]

To implement the same in your example, try this version:

col1, col2 = '{} has scored:','{}/10'

with open('classA.csv', 'a') as fp:
   writer = csv.writer(fp, delimiter=',')
   data = [(col1.format(name), col2.format(score))]
   writer.writerows(data)

You also don't need to add the \\n

Answer 2

您的定界符是'，'，所以您应该尝试： data = [("{0} has scored,{1} / 10\\n ".format(name,score))]或将定界符设置为'：'
