file = open('example.txt', 'r') data = file.read() print(data) Reading a File Line-By-Line Sometimes, you may want to read a file line-by-line. To do that, you can use aforloop to loop through the file line-by-line. The following code demonstrates how to read a file line-...
File"<stdin>", line1,in<module> FileNotFoundError: [WinError2] The system cannot find the file specified:'C:/ThisFolderDoesNotExist' 没有改变工作目录的pathlib函数,因为在程序运行时改变当前工作目录往往会导致细微的 bug。 os.getcwd()函数是以字符串形式获取当前工作目录的老方法。
Work through the definition of @timer line by line. Make sure you understand how it works. Don’t worry if you don’t get everything, though. Decorators are advanced beings. Try to sleep on it or make a drawing of the program flow. Note: The @timer decorator is great if you just ...
