Question

我一直试图让这段代码工作一段时间，而对于我的生活，我找不到问题。尝试打开并读取文本文件时，出现“无此文件或目录”错误。该文件在我的桌面上，所以我知道我没有使用错误的名称。

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

        # Prompt for file name
        fileName = input('Please Enter File Name: ')
        # Open the specified file for reading
        file = open(fileName, 'r')

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

        # Close file
        file.close()

    # Call the main function.
    main()

您可能需要指定文件的完整路径。

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

        # Prompt for file name
        fileName = input('Please Enter File Name: ')
        # Open the specified file for reading
        file_path = path.join(r'C:\Users\jblow\Desktop', fileName)
        file = open(fileName, 'r')

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

        # Close file
        file.close()

    # Call the main function.
    main()

你打算

吗？

def main():
    ...

和

    main()

在不同的缩进级别？或者这只是输入问题时的格式问题？我知道这可能不是答案，但是不时会让我感到沮丧......：）

任何人都可以在此代码中找到错误吗？我卡住了:(
