Python printing two things on one line

February 22, 2017, at 11:03 PM

I'm working through the edx python course. I've done everything correctly in the last assignment. However, I'm struggling with this print issue.

I have a function displayHand(hand) which essentially takes a dictionary with keys being letters and values be the number of occurrences of the letters. The function then prints a string with each key appearing the same number of times as its value. So for example if

hand={a:3, b:4, c:1}
displayHand(hand)=a a a b b b b c

Now in the program for any given hand it wants me to display it using the displayHand function with the text "current hand: "

Again, if hand={a:3, b:4, c:1} the program should display

current hand: a a a b b b b c

How do I do this with a print statement? I've tried print("current hand"+str(displayHand(hand)), but this first evaluates the function and then just prints None. I can't put print("Current Hand: ") and displayHand(hand) directly underneath, because then they print on different lines. I need to get them to print on the same line.

Answer 1

Python 3:

def displayHand(dct):
    for key, val in sorted(dct.items()):  # sorted if key order should be abc
        print((key + " ") * val, end="")

hand = {"a": 3, "b": 4, "c": 1}
print("current hand: ", end="")

Notice the end="" which appends whatever is inside "". The default setting is end="\n". In this case, we will just use an empty string. See here and here.


current hand: a a a b b b b c 
Answer 2

That should work for you :

print("current hand: ", end="")

In print() function default end is new line. In the code above you just change it to whatever you want.

Answer 3

You could do the following:

def displayHand(hand):
    print('{} {}'.format('current hand:', ' '.join([' '.join([li] * ni) for li, ni in sorted(hand.items())])))

That creates a string first which is then printed.



prints the desired output:

current hand: a a a b b b b c
Answer 4

You can use print twice, you just have to add a comma after the first print ex: print("a"), print("b").

Answer 5

Check out this thread, it shows some examples of using commas at the end of the line and other sys tools
