In python, ___________ method is used to write multiple strings to a file?a)writelines()b)write()c)read()d)readline()Correct answer is option 'A'. Can you explain this answer?

Question

Answer

Concept:
writelines() method :
This method is used to write multiple strings to a file. We need to pass an iterable object like lists, tuples, etc. containing strings to the writelines() method. Unlike write(), the writelines() method does not return the number of characters written in the file.

write() method:
write() method takes a string as an argument and writes it to the text file. It returns the number of characters being written on single execution of the write() method. Also, we need to add a newline character ( ) at the end of every sentence to mark the end of the line.

read() method:
This method is used to read a specified number of bytes of data from a data file.

readline([n]) method:
This method reads one complete line from a file where each line terminates with a newline ( ) character. It can also be used to read a specified number (n) of bytes of data from a file but maximum up to the newline character ( ).
Hence the correct answer is writelines().

Answer

Explanation:

writelines() method:
- The writelines() method in Python is used to write multiple strings to a file.
- It takes a list of strings as input and writes each string in the list to the file.

Example:
python
# Open a file in write mode
file = open('example.txt', 'w')

# List of strings to write to the file
lines = ['Hello,','This is an example','Writing multiple lines using writelines method']

# Write the list of strings to the file
file.writelines(lines)

# Close the file
file.close()

Explanation of the Example:
- In this example, we open a file named 'example.txt' in write mode.
- We create a list of strings called lines that we want to write to the file.
- We use the writelines() method to write each string in the lines list to the file.
- Finally, we close the file to ensure that all the data is written properly.

Conclusion:
- The writelines() method is useful when you want to write multiple lines of text to a file in Python. It simplifies the process of writing multiple strings to a file by taking a list of strings as input.
