I'm trying to read a file in python (scan it lines and look for terms) and write the results- let say, counters for each term. I need to do that for a big amount of files (more than 3000). Is it possible to do that multi threaded? If yes, how? So, the scenario is like th...
file=open('text.txt')lines=file.readlines()forlineinlines:print(line)file.close() 逐行读取,每次一行 使用readline()方法可以将文件中的内容逐行读取,每次调用返回一行,所以需要遍历来读取全部内容,但是占用内存最小,因为不是将文件中的所有内容一次读出: ...
python的read、readline、redalines都是读取文件的方法,下面以具体案例讲解它们之间的区别: 首先给出一个要读取的文件: python is very good java is very good c++ is very good 使用read读取文件,会返回整个文件的内容,结果如图所示, f = open("保存字符串.txt","r")#返回一个文件对象 ...
