[英]writing a list as csv in Python
我在Phyton中有类似的清单:
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'.
我想保存一个csv或txt文件,其输出应如下所示:
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
我一直在尝试:
for item in mylist:
mylist.write("%s/n" % item)
但是我得到:
AttributeError: 'list' object has no attribute 'write'
我应该如何进行?
提前致谢!
这看似微不足道,但是我没有找到任何重复的答案来回答这个特定的简单问题(花了几分钟寻找它们!),所以这是我的建议:
with open("output.txt","w") as f:
for i,item in enumerate(mylist,1):
f.write("{}. {}\n".format(i,item))
mylist
是输入,不能write
。 您必须打开一个文件对象并遍历mylist
元素(使用enumerate
以1开始的索引对其进行压缩)。 /n
,它应该是\\n
(远离os.linesep
因为它将在Windows上加\\r
两次) 首先,您需要稍微更改列表,因为有时您使用'
是'
。 这是更正的列表:
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,您需要将值写入文件对象,而不是列表对象。
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()
如果希望输出具有示例中的行号,则可以使用此方法在列表和等于列表长度的数字列表上进行迭代:
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是一个列表对象,没有写功能。 因此,您得到了AttributeError。
您需要打开一个文件来写入一些数据,这是我的解决方案:
with open('output.txt', 'w') as f:
[f.write("%d. %s\n" % (i,v)) for i,v in enumerate(mylist, 1)]
您应该写入 file
而不是 list
对象,而且单引号错误 ,请尝试以下操作:
open('text.txt', 'a').write("\n".join(mylist))
