pandas 字符串拼接问题

[toyst]

import pandas as pd
df = pd.DataFrame(columns = ['a', 'b', 'c'],
             data=[['A','1','http:1'],
                   ['B', '2','http:2'],
                   ['C', '3','http:3'],
                   ['D','4','http:4']])
print(df)

   a  b       c
0  A  1  http:1
1  B  2  http:2
2  C  3  http:3
3  D  4  http:4

我想输出：

#Result
G "A","1"
http:1
G "B","2"
http:2
G "C","3"
http:3
G "D","4"
http:4

这样的格式，应该怎么拼接输出啊

[tfdetang]

这不就是行循环一下 把每列的内容放到格式化的字符串里就行了吗

[toyst]

@tfdetang 关键是这个 http:1 是个回车怎么拼接啊

[zhusimaji]

@toyst 回车自己加个\n

[cclin]

拿去抄吧
def combine(line: pd.Series):
print(line)
return f'G "{line.a}","{line.b}"\n{line.c}'


df = df.apply(combine, axis=1)

for s in list(df):
print(s)

[cassidyhere]

'G "' + df.a + '","' + df.b + '"\n' + df.c

感谢大家，原来输出到文本\n 就能显示换行符了
