You cannot have else without a preceding if statement.

And btw If user enters value between 2.0 and 1.0 this program will do nothing, address that range too.

An "else:" is part of an "if: ... elif: ... else: ..." structure
Why so you have an "else" alone at this place ?
if no reason, just remove it.

IndentationError: unexpected indent

In Python, indentation matters, you can't indent for no reason, the "if" structure should be at same level as first line.

This one isn't willing to learn - check his other question. :sigh:

This is your code:

weight=0.0
weight=float(input("Enter a weight in kilograms:"))

else:
    if (weight >=5.0):
        print("Open Green gate.")
    elif(weight >=2.0):
        print("Open Red gate.")
    elif(weight <= 1.0):
        print("Open Yellow gate.")

You cannot write else without an "if" statement and there is no "if" statment before the first "else". Either write an "If" statement that does something or remove the "else" and just write it like this:

weight=0.0
weight=float(input("Enter a weight in kilograms:"))


if (weight >=5.0):
    print("Open Green gate.")
elif(weight >=2.0):
    print("Open Red gate.")
elif(weight <= 1.0):
    print("Open Yellow gate.")
