Pass a value to x by asking the user to enter a number, which will be assigned to variable x. float converts the input number from a string to a floating point number.

x = float(input("Enter a number: ")) # Enter a value for x.
def fun2(x):
    return 2*x
a = fun2(x)
print(a)

You have passed function parameter as x in 3rd line. Either set x before passing argument or You should pass a number in third line like : a=fun2(4)

You did not pass a value to x. That‘s why.

When you call your function, you need to pass a value to it, for instance: 5.

a = fun2(5)
