What are the differences between readline() and readlines() in Selenium with python?

Selenium Web Driver Automation Testing Software Testing

The differences between readline() and readlines() methods are listed below.

readlines()

This method will read the entire content of the file at a time.
This method reads all the file content and stores it in the list.
This method reads up to the end of the line with readline () and returns a list.

readline()

This method will read one line in a file.
A new line character is left at the string end and is ignored for the last line provided the file does not finish in a new line.
This method reads up to the end of the line with readline() and returns a list.

Example

Code Implementation with readline()

#open the file for read operation
fl = open('pythonfile.txt')
# reads line by line
ln = fl.readline()
while ln!= "":
print(ln)
ln = fl.readline()
#close the file
fl.close()

Code Implementation with readlines()

#open the file for read operation
fl = open('pythonfile.txt')
# reads line by line and stores them in list
for ln in fl.readlines():
print(ln)
#close the file
fl.close()
