contents=f.read()print(contents) finally:iff: f.close() 2、使用with open() 每次都写close()比较繁琐,Python引入with语句,这样能够确保最后文件一定被关闭,且不用手动再调用close方法,效果和前面的try … finally是一样的。 注意:调用read()会一次性读取文件的全部内容 with open(r'text_files.txt','r'...
fileContent = file.read() file.close() #读取完后要关闭文件,增加文件安全性 print(fileContent) 1. 2. 3. 4. 输出结果: first line second line third line 1. 2. 3. fileContent = file.readline() #first line 重复3次才可全部读取 fileContent = file.readlines() #['first line\n', 'secon...
Files opened in binary mode (including 'b' in the mode argument) return contents as bytes objects without any decoding. In text mode (the default, or when 't' is included in the mode argument), the contents of the file are returned as str, the bytes having been first decoded using a ...
单纯的读取一个文件,我们首先要打开文件,然后读取里面的内容,使用read()方法,读取文件的全部内容,然后把读取出来的内容进行赋给一个变量;如下所示: file_reader.py with open('pi_digits.text') as file_object: contents = file_object.read() print(type(contents)) ...
>>>p.read_text() 'Text file contents' 更多详情可参见pathlib模块[1]。 fileinput 如果你只想读取一个文件,使用open()。如果需要实现文件列表的批量循环操作,不妨使用本模块。 fileinput.input input是fileinput模块的初始接口,其使用也是较简单。
>>>p=Path('my_binary_file')>>>p.write_bytes(b'Binary file contents')20>>>p.read_bytes()b'Binary file contents'>>>p=Path('my_text_file')>>>p.write_text('Text file contents')18>>>p.read_text()'Text file contents' 更多详情可参见pathlib模块[1]。

contents = f.read() print(contents) 输出结果如下: Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. ... 以下示例使用 readlines() 方法读取文件,返回了一个字符串列表: lines = [] with open('the-zen-of-python.txt') as f: ...
In this tutorial, you’ll learn how to open a file in Python. The data can be in the form of files such as text, csv, and binary files. To extract data from these files, Python comes with built-in functions to open a file and then read and write the file’s contents. ...
