Using the goto Statement in Python with the goto‑statement Package

Developers familiar with C know the goto statement can jump arbitrarily between code locations, but many experienced programmers warn against its use because it can make program logic extremely confusing.

Sometimes goto can be handy—for example, to break out of deeply nested loops or to jump to a specific point in the code—yet overusing it makes the code behave like a chaotic quantum system that is hard to control.

The final piece of advice is simple: avoid goto whenever possible.

To use goto in Python, you first need to install a third‑party package because the language does not provide a built‑in goto statement: pip install goto-statement Below is the syntax and a concrete example showing how to define a function with the @with_goto decorator and use labels and goto statements to implement a range‑like loop:

from goto import with_goto
@with_goto
def range(start, stop):
    i = start
    result = []
    label .begin
    if i == stop:
        goto .end
    result.append(i)
    i += 1
    goto .begin
    label .end
    return result
