python - 如何在Python中每个等级后插入3个空行

Question

我正在将不同的 csv 文件合并到一个新的 csv 文件中。第一个 csv 文件是缺席者的，在新的 csv 文件中，我希望在缺席者数据之后输入 3 个空行。 第二个 csv 文件是每个年级在场人员的列表。我想在每个成绩后插入 3 个空行。

到目前为止我的代码是:

import csv
with open('Inschool.csv') as f:
    reader =  csv.reader(f)
    in_school = list(reader)
with open('notinschool.csv') as f:
    reader =  csv.reader(f)
    not_in_school = list(reader)
for grade, name, status, hr_teacher in not_in_school:
    print grade, name, status, hr_teacher
for grade, name, status, hr_teacher in in_school:
    print grade, name, status, hr_teacher
iFile = open('Inschool.csv',)
reader = csv.reader(iFile)
IFILE = open('notinschool.csv')
READER = csv.reader(IFILE)
oFile = open('combined.csv','wb')
writer = csv.writer(oFile, delimiter='|', quoting=csv.QUOTE_ALL)
for row in READER:
    writer.writerow(row)
    writer.writerow([])
for row in reader:
    writer.writerow(row)

像这样吗？尝试将 lineterminator 参数添加到 csv.writer 作为 documented .

#!/usr/bin/python

import csv

with open('Inschool.csv') as f:
    reader =  csv.reader(f)
    in_school = list(reader)

with open('notinschool.csv') as f:
    reader =  csv.reader(f)
    not_in_school = list(reader)

for grade, name, status, hr_teacher in not_in_school:
    print grade, name, status, hr_teacher
for grade, name, status, hr_teacher in in_school:
    print grade, name, status, hr_teacher

iFile = open('Inschool.csv',)
reader = csv.reader(iFile)
IFILE = open('notinschool.csv')
READER = csv.reader(IFILE)
oFile = open('combined.csv','wb')
writer_a = csv.writer(oFile, delimiter='|', quoting=csv.QUOTE_ALL)
writer_b = csv.writer(oFile, delimiter='|', quoting=csv.QUOTE_ALL, lineterminator="\n\n\n\n")

for row in READER:
     writer_a.writerow(row)

writer_b.writerow([])

for row in reader:
     writer_b.writerow(row)
