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 th...
#使用绝对路径打开文件file_path ='E:\WorkSpace\python\coding\data.txt'#使用绝对路径,可读取系统任何地方的文件with open(file_path) as file_object: contents=file_object.read()print(contents) 3)逐行读取 上述都是一次读取data.txt中的内容,读取文件时,可能需要检查其中的每一行或者查找特定的信息,或者要...
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...
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...

read():直接读取出字符串,并且字符串或者字符对象返回。 readline():读取文本中的一行。 readlines():读取文本中的所有内容并放入缓存区,返回列表。 collections模块 collections是python内建的一个集合模块,提供了许多有用的集合类。OrderedDict可以实现一个 FIFO(先进先出)的 dict,当容量超出限制时,先删除最早添加的...
