#Write to an Existing File
#To write to an existing file, you must add a parameter to the open() function:
#"a" - Append - will append to the end of the file
#"w" - Write - will overwrite any existing content

f = open("demofile.txt", "a")
f.write("Now the file has one more line!")

f = open("demofile.txt", "w")
f.write("Woops! I have deleted the content!")
#Note: the "w" method will overwrite the entire file.

#Create a New File
#To create a new file in Python, use the open() method, with one of the following parameters:
#"x" - Create - will create a file, returns an error if the file exist
#"a" - Append - will create a file if the specified file does not exist
#"w" - Write - will create a file if the specified file does not exist


f = open("myfile.txt", "x")
#Result: a new empty file is created!

#Create a new file if it does not exist:

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