fileinput 内置了两个勾子函数: fileinput.hook_encoded(encoding,errors=None)使用gzip和bz2模块透明地打开 gzip 和 bzip2 压缩的文件 fileinput.hook_compressed(filename,mode)使用给定的 encoding 和 errors 来读取文件。 从标准输入中读取 若input()不传任何参数时,fileinput默认会以stdin作为输入源。 运行stdin...

首先介绍两个函数和一个符号‘.':txt = open(filename)、 txt.read() open():打开文件名了,需要在括号内键入文件的名称,而且可以将open()的结果赋值给一个变量,本文是复制给 变量txt。 read(): 读取文件的函数,也可以将读出的结果赋值给一个变量 ...
Importing text data with NumPy's loadtxt() NumPy'sloadtxt()is designed to read arrays of numbers from a text file; however, it can be used to read lines of text. This is convenient if you are using NumPy in the rest of your analysis, as the output is a NumPy array. ...
This continues to the end of the line and then wraps back around. If no argument is passed or None or -1 is passed, then the entire line (or rest of the line) is read. .readlines() This reads the remaining lines from the file object and returns them as a list....
