There are three ways to read the contents of a text file: read(), readline(), and readlines().1、read()方法 read（）方法表示一次读取文件全部内容，该方法返回字符串。The read() method means reading the entire contents of the file at once, and the method returns a string.2. The readline...
read_file.py #!/usr/bin/python with open('works.txt', 'r') as f: for line in f: print(line.rstrip()) The example iterates over the file object to print the contents of the text file. $ ./read_file.py Lost Illusions Beatrix Honorine The firm of Nucingen Old Goriot Colonel ...
因为read()到达文件末尾时返回一个空字符串,而将这个空字符串显示出来时就是一 个空行。消除空行可以print(contents.rstrip()),rstrip()删除(剥除)字符串末尾的空白。 逐行读取文件 filename ='d:/pi_digits.txt'with open(filename) as file_object:forlineinfile_object:print(line.rstrip()) 通过列表一行...
Namespaces are one honking great idea -- let's do more of those! 以下示例使用 read() 方法读取了该文件中的内容,并将其存入一个字符串对象: with open('the-zen-of-python.txt') as f: contents = f.read() print(contents) 输出结果如下: Beautiful is better than ugly. Explicit is better ...
2. declare a *string* variable that holds *the path to the text file*, =test.txt= >>> strPath="/home/kaiming/Documents/Python/text/text.dat" 3. open the file using the =open()= function >>> f=open(strPath) 4. Read the contents of the file using the =read()= function ...
Reading N Bytes From The File Reading and Writing to the same file Reading File in Reverse Order Reading a Binary file Access Modes for Reading a file To read the contents of a file, we have toopen a filein reading mode. Open a file using the built-in function calledopen(). In addit...
with open(file_path) as file_pi: # 打开特定路径下的文件 contents = file_pi.read() # 将读取到的文件内容存放在一个变量中 print(contents.rstrip()) # 打印文件内容并删除掉末尾的空白 1. 2. 3. 4. 5. 运行结果如下图所示。 与上面例子的运行结果一致,我们掌握了这种方法就可以读取任意路径下的...
This lesson will teach you how to read the contents of an external file from Python. You will also learn how to use the python csv module to read and parse csv data, as well as the json module to read and parse json data. #f = open('animals.csv')#for line in f:#print(line)#...
contents = file_object.read() print(contents.rstrip()) 我们在前面的文章说过,Python方法rstrip()删除字符串末尾的空白。现在,输出与原始文件的内容完全相同: 3.1415926535 8979323846 2643383279 文件路径 将类似于pi_digits.txt的简单文件名传递给函数open()时,Python将在当前执行的文件(即.py程序文件)所在的目录...
