我有一个嵌套列表,每个嵌套列表都有多个字符串:
[['http:/house.com/06','http:/google.com/09','http:6000.com'],['http:/house.com/04','http:/google.com/03','http:600.com', 'http://900.com],['http:/house.com/09','http:/google.com/076','http://rather.com']...]
我的目标是在第一列中获取每个列表的第一个元素,并在第二列和第三列中获取其余元素
想要在csv文件中得到结果:
col1 col2 co3 col4
http:/house.com/06 http:/google.com/09 http:6000.com
http:/house.com/04 http:/google.com/03 http:600.com http://900.com
http:/house.com/09 http:/google.com/076 http://rather.com
有办法做到这一点吗?

分隔符不应在标题行和数据行中更改。由于您在几行中有一个空字符串,因此应该使用逗号分隔符。试试吧:
pandas
:import pandas as pd
l1 = [['http:/house.com/06','http:/google.com/09','http:6000.com'],['http:/house.com/04','http:/google.com/03','http:600.com', 'http://900.com'],['http:/house.com/09','http:/google.com/076','http://rather.com']]
df = pd.DataFrame(data=l1, columns=['col1','col2','col3','col4']).fillna('')
df.to_csv('file1.csv', index=None)
这是数据框的样子:
csv
包:import csv
l1 = [['http:/house.com/06','http:/google.com/09','http:6000.com'],['http:/house.com/04','http:/google.com/03','http:600.com', 'http://900.com'],['http:/house.com/09','http:/google.com/076','http://rather.com']]
with open('file1.csv', 'w') as f:
rows = [['col1','col2','col3','col4']] + l1
writer = csv.writer(f)
writer.writerows(rows)

CSV文件列由COMMA(,)分隔,因此您可以迭代数据结构并将以下文本打印到文件中:
NgSwitch
你可以用嵌套的for循环来实现它
col1,col2,co3,col4
http:/house.com/06,http:/google.com/09,http:6000.com,
http:/house.com/04,http:/google.com/03,http:600.com,http://900.com
http:/house.com/09,http:/google.com/076,http://rather.com,
