If you're using Python >= 3.6: Use f-string

Ex:

age = input ("How old are you?\n");

height = input ("How tall are you ?\n");

weight = input("How much do you weigh?\n");

print(f"so , you're {age} year old, {height} ft tall and {weight} kg heavy.")

or str.format

Ex:

print("so , you're {0} year old, {1} ft tall and {2} kg heavy.".format(age, height, weight))

The format operator % works on a string, not on the entire print function, which always returns None. Also, you need to specify the format of the placeholders with specifications such as %s.

print("so , you're %s year old, %s ft tall and %s kg heavy." % (age,height,weight))

I'd use the .format() function like this;

age = input('How old are you? ')
height = input('How tall are you? ' )
weight = input('How much do you weigh? ')

print(("so, you're {} year old, {} ft tall and {} kg heavy").format(age,height,weight))
