的Python：將數據寫入到特定的細胞

Question

我需要一些數據，我需要把它寫入一個列，但以不同的字符串

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]) 

我想寫elem1與數elem2的細胞，我的意思是 111在A1 ，333 in A5等 我該怎麼做？

Answer 1

因此，根據list2最大索引，用空值初始化您的列表。然後，使用zip根據list1,list2索引/值元組填充它，就像您在嘗試中那樣。

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 

此時rows_to_write值得：

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

然後寫在1個指令中的行（不附加）

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

這將創建一個單行 「疏」 csv文件。 （open('hh1.csv', 'wb') as f for python 2）
