concatenating string with tuples in python

def print_distance(p1, p2):
    dist = (((p2[0]-p1[0])**2)+((p2[1]-p1[1])**2))**0.5
    d = print("{0:.2f}".format(dist))
    result = ("Distance between ", ','.join(p1) ," and ", ','.join(p2) ," is "+ d)
    return result
print_distance((0,1),(-1,-2))

TypeError: sequence item 0: expected str instance, int found I couldn't figure it out the output "Distance between (0, 1) and (-1, -2) is 3.16" I am beginner to this thing. Help me.

    result = ("Distance between ", ','.join(p1) ," and ", ','.join(p2) ," is "+ d)

this is line is just a bit of a mess maybe try using format the way you did elsewhere

    result = "Distance between {p1} and {p2} is {d}".format(p1, p2, d)

I'd like to give you more context but the gist of it is you are using join incorrectly.

your tuple contains ints so you cant join them with str.join. if you wanted to do that you would need to convert them first to str's. however to get the output you mentioned you can just use an fstring 

def print_distance(p1, p2):
    dist = (((p2[0]-p1[0])**2)+((p2[1]-p1[1])**2))**0.5
    print(f"Distance between {p1} and {p2} is {dist:.2f}")

print_distance((0,1),(-1,-2))

OUTPUT

Distance between (0, 1) and (-1, -2) is 3.16
