Three ways Python reads the contents of a file row by line _python

Method One:

Copy Code code as follows:

f = open ("Foo.txt") # Returns a File object
line = F.readline () # calls the ReadLine () method of a file
While line:
Print line, # followed by ', ' will ignore newline characters
# print (line, end = ') # used in Python 3
line = F.readline ()

F.close ()

Method Two:

Copy Code code as follows:

For line in open ("Foo.txt"):
Print line,

Method Three:

Copy Code code as follows:

f = open ("C:\\1.txt", "R")
lines = F.readlines () #读取全部内容
For line in lines
Print Line
