本文直接给出三种实现方法,代码例如以下. 方法一: f = open("Proc_Data.txt") # 返回一个文件对象 line = f.readline() # 调用文件的 readline()方法 while line: print line, # 后面跟 ',' 将忽略换行符 # print(line, end = '') # 在 Python 3中使用 line = f.readline() f.close() 方法二: for line in open("Pr
Python读取txt文件,有两种方式: (1)逐行读取 data=open("data.txt") line=data.readline() while line: print line line=data.readline() (2)一次全部读入内存 data=open("data.txt") for line in data.readlines(): print line
1 读取txt文件.跟c相比,python的文件读写简直是方便的可怕 首先是读取文件 首先获得文件名称,然后通过 open函数打开文件,通过for循环逐行读出文件内容 #!python file by ninahao 10.30 'readfile.py--read and display text file' #get filename fname=raw_input('enter file name:') print #attempt to open file for reading try
