跳过从 python 中的 CSV 文件读取一次的观察

Question

i read a CSV file with few columns and created a class for those columns:

  class member:
    name = ""
    vdate = []

data = []
for column in columns:
    m = member()
    m.name = column[1] + " " + column[2]
    m.date = int(column[5]

Now, i'm trying to skip lines that have been read once from m.name, the skiped lines wont be append to

data = []

However, after I skiped those lines, I want the date value in the skip lines to be append to the vdate [] in the class.

I tried:

  if m.name != m.name:
    data.append(m)
else:
    continue and vdate.append(m)

did not worked.

Answer 1

I do not think that a Class is the best way to go about this.

I would just have a simple dict to hold the name as a key and the date as a value. And then just check if each new line is in the dict. If it is not add it to the dict, and if it is just the date to a another list.

So that should give you a dict with key value pairs of names and dates, and a list with the dates where the name is already in the dict.
