[英]writing a list as csv in Python
我在Phyton中有類似的清單:
mylist ='thank you i love you ', 'my mom my biggest supporter’,’ my life line my best friend was a single parent worked 2 jobs to support us im so blessed to have her ’,’ as a mom and now shes my babys nonna happy mothers day mommy i love you', 'me and my mom love her to pieces'.
我想保存一個csv或txt文件,其輸出應如下所示:
1. thank you i love you
2. my mom my biggest supporter
3. my life line my best friend was a single parent worked 2 jobs to support us im so blessed to have her
4. as a mom and now shes my babys nonna happy mothers day mommy i love you
5. me and my mom love her to pieces
我一直在嘗試:
for item in mylist:
mylist.write("%s/n" % item)
但是我得到:
AttributeError: 'list' object has no attribute 'write'
我應該如何進行?
提前致謝!
這看似微不足道,但是我沒有找到任何重復的答案來回答這個特定的簡單問題(花了幾分鍾尋找它們!),所以這是我的建議:
with open("output.txt","w") as f:
for i,item in enumerate(mylist,1):
f.write("{}. {}\n".format(i,item))
mylist
是輸入,不能write
。 您必須打開一個文件對象並遍歷mylist
元素(使用enumerate
以1開始的索引對其進行壓縮)。 /n
,它應該是\\n
(遠離os.linesep
因為它將在Windows上加\\r
兩次) 首先,您需要稍微更改列表,因為有時您使用'
是'
。 這是更正的列表:
myList = 'thank you i love you ', 'my mom my biggest supporter', ' my life line my best friend was a single parent worked 2 jobs to support us im so blessed to have her ', ' as a mom and now shes my babys nonna happy mothers day mommy i love you', 'me and my mom love her to pieces'
其次,您需要將值寫入文件對象,而不是列表對象。
file_object = open('the_output_file_name.txt', 'w') #creates a file
for item in myList:
file_object.write("%s\n" % item) #writes the item to the file
file_object.close()
如果希望輸出具有示例中的行號,則可以使用此方法在列表和等於列表長度的數字列表上進行迭代:
file_object = open('the_output_file_name.txt', 'w') #creates a file
for item, number in zip(myList, range(len(myList))): #loop over myList and a range()
file_object.write("%d. %s\n" % (number + 1, item)) #writes the item to the file
file_object.close()
mylist是一個列表對象,沒有寫功能。 因此,您得到了AttributeError。
您需要打開一個文件來寫入一些數據,這是我的解決方案:
with open('output.txt', 'w') as f:
[f.write("%d. %s\n" % (i,v)) for i,v in enumerate(mylist, 1)]
您應該寫入 file
而不是 list
對象,而且單引號錯誤 ,請嘗試以下操作:
open('text.txt', 'a').write("\n".join(mylist))
