вызов файла с другой функции

Question

def file():

    pd = input("are you a new user?") 

    if pd == "yes": 
     print ("add your details") 

    age = int(input("how old are you?"))

     total = (totaldistance, totaltime, speed)

      content = [x.strip('\n') for x in f.readlines()]** 
      age = lines[0] 
      weight = lines [3] 
      height = lines [4]  
     totaldistancec = int(input("what was the total distance you cycled in KM?")) 
     totaltimec = int(input("how long did you cycle for in minutes?"))

     totalc = (totaldistancec, totaltimec, speedc) 
     Cycling_file.write(str(totalc)) 
     Cycling_file.close() 
     Personaldetails_file.close() 

Вот большая часть моей программы. Мне нужно открыть файл, который я создал в python, но используя другую функцию. как снова открыть файл в другой функции? Большая часть этого вопроса не имеет отношения к моему вопросу. детали, в которых мне нужна помощь, выделены жирным шрифтом.

Answer 1

изменение

with open(Personaldetails_file) as f: 

в

with open("Personaldetails_file.txt") as f: 

Вы объявили переменную «Personaldetails_file» в первый раз в функции перд(), так что он доступен только из этой функции (переменная сфера является эта функция).

Другой способ: использовать переменную в другом месте, объявить ее вне любой функции в верхней части кода.
