• Opens text file to be read

• Opens text file for appending text, adds data to end, creates new file if file doesn't exist.

What does the syntax - .read() do?

• read the text file line by line and return all the lines as strings

• reads all text from a file into a string or specific number of characters

• read all the lines of the text file and return them as a list of strings

What does the syntax - .readline() do?

• read the text file line by line and return all the lines as strings

• reads all text from a file into a string

• read all the lines of the text file and return them as a list of strings

What does the syntax - .readlines() do?

• read the text file line by line and return all the lines as strings

• reads all text from a file into a string

• read all the lines of the text file and return them as a list of strings

When opening a text file was does 'w' do?

f=open("File.txt","w")

• Opens text file for reading text

• Opens text file for appending text, adds data to end, creates new file if file doesn't exist.

• Opens text file for writing text, creates new file and overwrites data if file exists.

When opening a text file was does 'a' do?

f=open("File.txt","a")

• Opens text file for reading text

• Opens text file for appending text, adds data to end, creates new file if file doesn't exist.

• Opens text file for writing text, creates new file and overwrites data if file exists.

Identify the line of code to open a text file called space so that you can add data to the end of it.

• file.close()

• file.open("space.txt","w")

• file.open("space.txt","a")

• file.open("space","a")

Identify the line of code to close the text file so that no more data can be written to it.

• file.close()

• file.open("space","w")

• file.open("space","a")

• file.open("space","r")

Identify the line of code to create a new text file called space and write data to it

• file.close()
