Question

我正在尝试插入文件，并且在line = infile.redline()

行上出现语法错误

def main():
  # Declare variables
  line = ''
  counter = 0

  # Prompt for file name
  fileName = input('Enter the name of the file: ')

  # Open the specified file for reading
  infile = open('test.txt', 'r')

  # Priming read
  line = infile.redline()
  counter = 1

  # Read in and display first five lines
  while line != '' and counter <= 5:
  # Strip '\n'
    line = line.rtrip('\n')
    print(line)
    1ine = infile.readline()
    # Update counter when line is read
    counter +=1  

# Close file
infile.close()

# Call the main function.
     main()

Answer 1

rtrip应为rstrip。 redline应为readline。 infile.close()应缩进，main()不应该缩进。

然而，最严重的问题是：

1ine = infile.readline()

第一个角色是一个，而不是L。

Answer 2

了解标准库可以让您的生活更轻松！

from itertools import islice

def main():
    fname = input('Enter the name of the file: ')

    with open(fname) as inf:
        for line in islice(inf, 5):    # get the first 5 lines
            print(line.rstrip())

if __name__=="__main__":
    main()

Answer 3

不是redline而是readline：

line = infile.redline()

这段代码有什么问题？我正在尝试插入此文件
