将python字典写入文件

Question

I'm trying to split a csv file into multiple files, preserving the header each time: So if my current original file is :

 <t> ID    Name   Position  <br> 1    Jose     Engineer <br> 2  Maria  Developer <br> 3 Keith  Manager</t>

I want to split it into 3 files :

File1.txt

<t> ID    Name   Position  <br> 1    Jose     Engineer <br>

File2.txt

<t> ID    Name   Position  <br> 2    Maria     Developer <br>

File3.txt

<t> ID    Name   Position  <br> 3    Keith     Manager <br>

I am able to build the key-pair dictionary, but if I use

json.dump(keys, file_ptr, ensure_ascii=False

I get unwanted [ and ] at the beginning and end of keys' list.

I also tried

writer = csv.writer(file_ptr)
writer.writerows(keys)

which splits each letter of the key like N , a , m , e , and so on.

Any suggestions?

Also, is it possible to avoid iterating over the keys in the dictionary while printing the corresponding values?

Change your csv code to use single row:

writer.writerow(keys)

or wrap the keys into a list:

writer.writerows([keys])
