Using Lists as Dictionary Values

[bfallert]

Here is the code. The data comes from a file with lines of 15 pieces of text separated by a space. The first piece of text in each line will become the 'key' and a temporary list is made of other pieces of text and that list is to be the 'value' for the respective 'key'. Each time through, the new key is added, but, after all the data is processed, every key ends up with the same list as the value.

for new_line in data:
    new_line = new_line.strip()
    print(f'\n{new_line} : Line Length = {len(new_line)}')

    # read in the rd info / split on whitespace
    rd_info = list(new_line.split())
    print(rd_info)

    # create dictionary
    temp_list.clear()

    rd_name = rd_info[0]
    rd_age = int(rd_info[3])
    rd_yr = int(rd_info[6])
    rd_yr_left = rd_yr
    rd_wt = int(rd_info[13])
    rd_wt_left = rd_wt
    rd_fg = 0
    rd_stp = 0
    temp_list.append(','.join([str(rd_age), str(rd_yr), str(rd_yr_left), str(rd_wt), str(rd_wt_left), str(rd_fg), str(rd_stp)]))
    print(f'Temp List: {temp_list}')
    rd_dict[rd_name] = temp_list

print(rd_dict)
