为什么我在 python 中运行此代码时出现输入错误？

Question

import pickle
class salesrecord:
    def __init__(self):
        self.bedsheets = 0
        self.blankets = 0
        self.pillows = 0
        self.covers = 0
        self.address = 0
one_day_record = salesrecord()
one_week_record = [one_day_record for i in range(7)] # Make 1D Array to store records
binary_file = open("Record.DAT", "wb")  # open file to save records
for i in range(7): # Save each record in file
    pickle.dump(one_week_record[i], binary_file) 
print("File Created")
binary_file.close() # File Created
binary_file = open("Record.DAT", "rb") # File again open for reading

one_week_record = []
while True: # Read until EOF
    one_week_record.append(pickle.load(binary_file))
binary_file.close()
print(one_week_record)***

But it is giving this output

Traceback (most recent call last):
  File "E:/Python/New/New.py", line 27, in <module>
      one_week_record.append(pickle.load(binary_file))
EOFError: Ran out of input

Answer 1

Use try except to skip this particular error:

while True:
    try:
        one_week_record.append(pickle.load(binary_file))
    except EOFError:
        break
