How to realize the operation of multi-line read and write by python
This article will explain in detail how to achieve multi-line reading and writing operations in python. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
Basic read and write operations are necessary for us to learn python. In the basic read and write existence, you can consider multi-line read and write operations. Let's take a look at the multi-line read and write operations.
1. Write multiple lines at a time
Nums = ["one", "two", "three", "four", "five", "six", "seven"] t = open (r "g:\ t2.txt", "a") # append open file for get_one in nums: t.write (get_one+ "\ n") # write each element to the file in a loop, with\ nt.close () print ("continuous write complete") at the end of the line
2. Read one line at a time. F.readline (s), f represents a file opened in readable mode, and s is an optional parameter.
If you set a byte of the specified size, a string of the corresponding size is returned, or if not set, the string is returned in line units.
T1 = open (r "g:/t2.txt", "r") dd = 1while dd: dd = t1.readline () # read one line at a time print (dd.strip ()) # strip () removes the empty characters at both ends of the string
3. Read multiple lines in list format.
T1 = open (r "g:/t2.txt", "r") tweets = t1.readlines () # read multiline print in list format. This is the end of the article on "how to read and write multiline python".
