Question

如果找到用户输入的文件，则需要激活while循环，“ while”循环中有一个“ try”，如果找到该文件，则打开文件

def main():
  customer_file = input("Enter the name of the file ")
  while _____:
    try:
      input_file = open(customer_file, "r")
    except FileNotFoundError:
      print("Invalid file Name")

  line = input_file.readline()
main()

Answer 1

例如：

def main():
    while True:
        customer_file = input("Enter the name of the file ")
        try:
            with open(customer_file, "r") as input_file:
                # better to use contex manager (with open...) to handle the file
                line = input_file.readline()
            break
        except FileNotFoundError:
            print("Invalid file Name")


main()

成功找到用户输入的文件后，如何激活“ While”循环？
