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

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()
