CSVファイルからPythonを使ってすべてのパスを生成する

Question

私はcsvファイルからすべての可能なパスを生成するpythonを使ってプログラムを作成します。私はこれについてどうやって行くのですか？ - >アップル - > iPhone - > iPhone4.0

会社：下の画像では例えば

import pandas as pd 
import csv 

def dataInCol(fieldName): 
    df = pd.read_csv('..\\data.csv',usecols=[fieldName]) 
    qr = df.values.tolist() 
    flattened = [val for sublist in qr for val in sublist] 
    return flattened 


def makingPaths(dataCol, path = "Companies: "): 
    with open('..\\data.csv', "rb") as f: 
     reader = csv.DictReader(f) 
     headers = reader.fieldnames 
    for eachValue in dataCol: 
     path = path + str(eachValue) 
     if str(eachValue) in headers: 
      newCol = dataInCol(str(eachValue)) 
      makingPaths(newCol) 
     break 
    return path

これは宿題の質問のように思えるが、私はそれはので、ここで私がやったことだ興味深いが見つかりました：

csvfile = open('data.csv', 'r') #open the csv file 
lines = csvfile.readlines() # read the file into a list, one line per element 
headings = [cell.strip() for cell in lines[0].split(",")] #keep a clean list of headings 
splitlines = [] 
for line in lines[1:]: # split each row into cells 
    splitlines.append(line.split(",")) 
columns = zip(*splitlines); # convert rows to columns 

def recursePrint(colval, text): # a recursive function to traverse the columns 
     colval = colval.strip() 
     if (colval in headings): 
      for c in columns[headings.index(colval)]: 
       newtext = text + colval + "->" 
       recursePrint(c, newtext) 
     else: 
      print (text + colval) 


for x in columns[0]: 
    recursePrint(x, "") # run the recursion 

そして出力：
