with open('test.txt', 'w') as test: #This creates the file that I will use as an example. The w means 'write' (this means that I am writing data to the file)
    wl = ['hello\n','\n', 'world\n', '\n'] #these are the lines I'm writing. I have the \n after each word so that everything isn't all in one line.
    #Also, the lines that just have \n are blank lines since \n doesn't show up when you actually look at the text file
    test.writelines(wl) #this takes the table that I made on line 2 and writes the lines

with open('test.txt', 'r') as test: #This opens the file that I created on line 1. The r means read (this means I am reading data from the file)
    readlines = test.readlines() #This reads all the lines and puts it in a list
    print(readlines) #For testing sake, I have this here to show what the lines look like before removing the empty ones
    for i in readlines: #This is a for loop. What it does is it goes through the readlines list. 'i' is the item in the list that the loop is currently on.
        if i == '\n': #This checks if the line is just '\n' since lines that are just '\n' are blank
            readlines.remove(i) #This removes the line from the list if the line is just '\n'. It doesn't remove the line from the actual file though.
    print(readlines) #This prints what the table is after removing the empty lines
