I have a list in Phyton similar to:

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'.

I want to save a csv or txt file whose output should look like:

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

I’ve been trying with:

for item in mylist:
    mylist.write("%s/n" % item)

But I get:

AttributeError: 'list' object has no attribute 'write'

How shoul I proceed?

Thanks in advance!

  • also note that csv stands for comma-separated values, which is not really what you present as desired output. Commented Mar 17, 2017 at 21:20

That may seem a trivial one, but I didn't find any duplicates answering that particular simple question (looked for them for several minutes!) so here's my proposal:

with open("output.txt","w") as f:
    for i,item in enumerate(mylist,1):
        f.write("{}. {}\n".format(i,item))
  • mylist is an input, you cannot write into it. You have to open a file object and iterate on mylist elements (using enumerate to zip it with the indexes starting at 1).
  • also you wrote /n for linefeed character, which should be \n (stay away from os.linesep as it would add \r twice on Windows)

Thanks a lot. It was perfect.

First, you need to change the list slightly as sometimes you are using ’ instead the '. This is the corrected list:

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'

Secondly, you need to be writing the values to a file object, not a list object.

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()

If you want the output to have line numbers like in your example, you could use this which iterates over the list and over a list of numbers equal to the length of the list:

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 is a list object, which do not have write function. Therefore you got an AttributeError.

You need to open a file to write some data, and here's my solution:

with open('output.txt', 'w') as f:
    [f.write("%d. %s\n" % (i,v)) for i,v in enumerate(mylist, 1)]

You should write to a file not to a list object, also, the single quotes are wrong, try the following:

open('text.txt', 'a').write("\n".join(mylist))
