Question

我需要一些数据，我需要将它写入一列但不同的字符串

df = pd.DataFrame()
list1 = ['111', '333', '555', '777', '8888']
list2 = [1, 5, 56, 44, 2]
with open('hh1.csv', 'a') as f:
    writer = csv.writer(f)
    for (elem1, elem2) in zip(list1, list2):
        writer.writerow([elem1])

我想将elem1写入编号为elem2的单元格，我的意思是 111中的A1，333中的A5等我怎么能这样做？

Answer 1

因此，根据list2 max index，使用空值初始化列表。然后，使用list1,list2根据zip索引/值元组填充它，就像在尝试时一样。

list1 = ['111', '333', '555', '777', '8888']
list2 = [1, 5, 56, 44, 2]
rows_to_write = [[""] for _ in range(max(list2))]
for i,v in zip(list2,list1):
    rows_to_write[i-1][0] = v

此时rows_to_write值得：

[['111'], ['8888'], [''], [''], ['333'], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], ['777'], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], [''], ['555']]

然后在1条指令中写入行（不要追加）

with open('hh1.csv', 'w',newline='') as f: # python 3
    csv.writer(f).writerows(rows_to_write)

这会创建一个单行＆＃34;稀疏＆＃34; csv文件。（open('hh1.csv', 'wb') as f for python 2）

Python：将数据写入特定单元格
