這段代碼有什麼問題？我想插入這個文件

Question

我試圖插入一個文件，我不斷上線line = infile.redline()

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得到一個語法錯誤，應該是rstrip。 redline應該是readline。 infile.close()應該縮進，並且main()不應該是。

然而，最嚴重的問題是在這裏：

1ine = infile.readline() 

即第一個字符是一個，而不是L.

Answer 2

這不是redline但readline：

line = infile.redline() 

Answer 3

知標準庫可以讓你的生活更簡單！

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()
