有没有办法将for语句内容的内容传输到函数？

Question

def encrypt():
  while True:
    try:
        userinp = input("Please enter the name of a file: ")
        file = open(f"{userinp}.txt", "r")
        break  
    except:
      print("That File Does Not Exist!")
  second = open("encoded.txt", "w")
  for line in file:
    swapped(line)
    break
  #second.write()  
 
def swapped(line):
  newword = ""
  arranged = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"]
  random = ["q","w","e","r","t","y","u","i","o","p","a","s","d","f","g","h","j","k","l","z","x","c","v","b","n","m"]
  print(line)

因此，我目前正在尝试制作一个程序来加密，然后解密文件。对于加密过程，我试图将给定文件的一行移动到另一个函数，该函数将从与文件中的单词相对应的一个索引中替换一个索引，并在同一索引中使用字母在随机列表中。

到目前为止功能，整个列表被打印出9次，这是给定文件中的行数。在上方，我试图做到这一点，以便在for循环下调用交换功能，但随后断开，该功能仅将文件的一行传输到第二个功能，但使列表正常打印出字母。

目前，我只需要以单独运载到交换函数的方式传输文件内容的帮助，而且还以列表正常工作的方式使我可以交换值。

我仍然是Python的新手，因此将不胜感激。

如今，您交换功能只是打印输入，因为您实际上没有使用已安排的随机列表。我建议将列表更改为词典：

def encrypt():
  while True:
    try:
        userinp = input("Please enter the name of a file: ")
        file = open(f"{userinp}.txt", "r")
        break  
    except:
      print("That File Does Not Exist!")
  second = open("encoded.txt", "w")
  encrypted_lines = []
  #Creates a list of encrypted lines
  for line in file:
     encrypted_line = swapped(line)
     encrypted_lines.append(encrypted_line)
  return encrypted_lines
  #TODO save to encrypted file instead of returning
 
def swapped(line):
    new_line = ""
    encrypt_dict =  {'a': 'q', 'b': 'w', 'c': 'e', 'd': 'r', 'e': 't', 'f': 'y', 'g': 'u', 'h': 'i',
    'i': 'o', 'j': 'p', 'k': 'a', 'l': 's', 'm': 'd', 'n': 'f', 'o': 'g', 'p': 'h',
        'q': 'j', 'r': 'k', 's': 'l', 't': 'z', 'u': 'x', 'v': 'c', 'w': 'v', 'x': 'b',
    'y': 'n','z': 'm'}
    for i in line:
        if i in list(encrypt_dict.keys()):
            new_line = new_line + encrypt_dict[i]
    return new_line
print(encrypt())
