Python将一列数据转换为多列

Question

The question i have is: I have a dataset that looks like this (let's say there is one variable called "ChatConversations" and another called CustomerID) and that has the text of the chat for each customer. Suppose, there are 1000 customers, so my dataset has 1000 rows with 2 columns, one for CustomerID and another for the Chattranscript. Suppose each customer has 2 sentences each. So, i want to create a new dataset/file, which has 2000 sentences appended to each other, like a paragraph,which i will then read and do text mining on.

Hopefully my question is clear

Output data like below: I love thes service.IT took time.The issue was resolved, so I don't have complaints.The agent couldn't understand what I said.Grett job no complaints.Can do better (basically all the values of the "ChatCOnversation" variable need to be joined together to create a paragraph/text file kind of thing

Answer 1

You could make a dictionary for each row which you create by zipping a list of column headlines and each data line together and store those in a list, like this:

headlines = ["India", "Asia", "Singapore", "Malaysia", "Nepal", "China"]
dict_list = []
with open("my_file.csv") as csv_file:
    for line in csv_file:
        dict_list.append(dict(zip(hl, [item.strip() for item in line.split(",")])))  
print(*dict_list, sep="\n")  # print one dictionary per line

Update:

You probably want just something like this:

with open("input.csv") as in_file, open("output.txt", "w") as out_file:
   for line in in_file:
        content = line.split(",", 1)[1].strip()
        print(content, file=out_file)
