How do you convert float to string using def?

Question

I found out that if you say something like:

user=float(5) #user is a float
s=(user) + (2) #equation solved as float
user=str(user) #user is a string
w=(user) + (" is a number") #equation solved as string

You essentially converted a float into a string. So in between those two lines you could write an equation and it would then solve as a float then after you converted it into a string you could write an equation and it solve it as a string. So my question is how do you do that as a def statement? I tried:

user=float(12) #user is a float
def convert(x): #variable is supposed to convert into string
x=str(x)
user(convert) #thus user should be converted into a string.

But it doesn't convert into a string, it is still defined as a float. Is there a way to convert a variable into a string using def?

Answer 1

your code should be like this
user = float(12)
def convert(x):
x=str(x)
return x
user = convert(user)

Answer 2

Mahendra is correct, but why you need a def to convert when you can use w=str(user) + " is a number"
?

Answer 3

it seems you meant convert(users) instead of users(convert). The one issue i can think of is the namespace. Because the conversion happens inside the def function, if you use x, it would give you a string, but if you use 'user' it will return a float.

Answer 4

I have a bunch of formal floats that need to be converted into strings for various reasons. Thank you Mahendra!
