Perfect! Now, let's see how the 'a' (append) mode works. As we said before, it is used to add new information to the end of a file without overwriting its existing contents:
file = open('employees.txt', 'a')
file.write('\nKate Smith, Junior Python Developer')
file.close()
By using the 'a' mode in the open() function, we could add a new employee to our list instead of deleting all the other employees. Note that we started with '\n', which is a newline character.
Open the daily_sales.txt file in the append mode. Add the following three lines at the end of the file:
Day 8 (Monday): 19432.19 Day 9 (Tuesday): 18233.76 Day 10 (Wednesday): 23432.43
Start with:
file = open('daily_sales.txt', 'a')
Remember about using \n to introduce new lines.
