方法一:

代码如下:


f = open("foo.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:

代码如下:


for line in open("foo.txt"): 
    print line, 

方法三:

代码如下:


f = open("c:\\1.txt","r") 
lines = f.readlines()#读取全部内容 
for line in lines 
    print line
