Readline printing just characters

I run this code in the Python IDLE, and it will only return the amount of letters specified instead of the line specified. 

 if os.path.exists(saveDir + name + '.txt') == True:
    print('welcome back ' + name + '.')

    file = open(saveDir + name + '.txt')
    race = file.readline(1)
else:
    race = intro()

When I print the race variable, it comes out as the G (The input name is Grant). The text file looks like this

Grant
Human

What Am I doing wrong?

    print('welcome back ' + name + '.')

    file = open(saveDir + name + '.txt')
    race = file.readline() # this reads one line at a time
    raceType = file.readline() # this will give you the second line (human)
else:
    race = intro()

race = file.readline(1) returns 1 byte (character) of the line (see here). You want to return the entire line so call race = file.readline().

Are you trying to read a single line, or all the lines? file.readline() will return the first line of the file as a string. If called again, it will return the second line, and so on. You can also load all the lines of the file as a list with file.readlines(), and then get the first or second element by using [0] or [1], so file.readlines()[1] will yield "Human".
