Parsing text file in Python into a dictionary

问题

I have a csv file. I want to create dictionary from this data.I should not pandas. Data looks like this:

I do this. But size of the numbers is not same. How can I create a dictionary?

filename=" data.dat"
file=open(filename, encoding="latin-1").read().split(' , ')
dictt={}

for row in file:
    dictt[row[0]] = {‘values’, row[1]}

I have a file as above. First, I need to create a dict. After that, I will print the daily number of unique measurements in desending order according to date.

Hi
That will do what you want

with open("./test.txt") as myFile:
    formattedData = dict()
    for line in myFile:
        try:
            date , numbers = line.split(' , ')
            numbers = numbers.replace("\n","") 
            numbers = numbers.split(',')
            formattedData[date] = len(list(set(numbers)))
        except:
            date = line
            formattedData[date] = 0
print(formattedData)

Firstly, do not call your variables 'list' as that is a python keyword and it will cause confusion. I can't reproduce this because I don't have the file, but I think changing the line in the for loop to this should work.

newvariablename[row[0]] = row[1]
