我用函数解决了这个问题。我唯一做的就是改变函数的标签。下面是一个非常基本的代码:

def goto_holiday(): #label: holiday
        print("I went to holiday :)")
    
def goto_work(): #label: work
    print("I went to work")
salary=5000
if salary>6000:
    goto_holiday()
else:
    goto_work()

通过一些工作，在python中添加类似“goto”的语句在技术上是可行的。我们将使用"dis"和"new"模块，这两个模块对于扫描和修改python字节代码都非常有用。

实现背后的主要思想是首先将代码块标记为使用“goto”和“label”语句。一个特殊的“@goto”装饰器将用于标记“goto”函数。然后，我们扫描这两个语句的代码，并对底层字节代码应用必要的修改。这一切都发生在源代码编译时。

import dis, new

def goto(fn):
    """
    A function decorator to add the goto command for a function.

        Specify labels like so:
        label .foo

        Goto labels like so:
        goto .foo

        Note: you can write a goto statement before the correspnding label statement
    """
    labels = {}
    gotos = {}
    globalName = None
    index = 0
    end = len(fn.func_code.co_code)
    i = 0

    # scan through the byte codes to find the labels and gotos
    while i < end:
        op = ord(fn.func_code.co_code[i])
        i += 1
        name = dis.opname[op]

        if op > dis.HAVE_ARGUMENT:
            b1 = ord(fn.func_code.co_code[i])
            b2 = ord(fn.func_code.co_code[i+1])
            num = b2 * 256 + b1

            if name == 'LOAD_GLOBAL':
                globalName = fn.func_code.co_names[num]
                index = i - 1
                i += 2
                continue

            if name == 'LOAD_ATTR':
                if globalName == 'label':
                    labels[fn.func_code.co_names[num]] = index
                elif globalName == 'goto':
                    gotos[fn.func_code.co_names[num]] = index

            name = None
            i += 2

    # no-op the labels
    ilist = list(fn.func_code.co_code)
    for label,index in labels.items():
        ilist[index:index+7] = [chr(dis.opmap['NOP'])]*7

    # change gotos to jumps
    for label,index in gotos.items():
        if label not in labels:
            raise Exception("Missing label: %s"%label)

        target = labels[label] + 7   # skip NOPs
        ilist[index] = chr(dis.opmap['JUMP_ABSOLUTE'])
        ilist[index + 1] = chr(target & 255)
        ilist[index + 2] = chr(target >> 8)

    # create new function from existing function
    c = fn.func_code
    newcode = new.code(c.co_argcount,
                       c.co_nlocals,
                       c.co_stacksize,
                       c.co_flags,
                       ''.join(ilist),
                       c.co_consts,
                       c.co_names,
                       c.co_varnames,
                       c.co_filename,
                       c.co_name,
                       c.co_firstlineno,
                       c.co_lnotab)
    newfn = new.function(newcode,fn.func_globals)
    return newfn


if __name__ == '__main__':

    @goto
    def test1():
        print 'Hello' 

        goto .the_end
        print 'world'

        label .the_end
        print 'the end'

    test1()

希望这回答了问题。

我最近写了一个函数装饰器，在Python中启用goto，就像这样:

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

我不知道为什么有人想做这样的事情。也就是说，我并不是很认真。但我想指出的是，这种元编程在Python中实际上是可能的，至少在CPython和PyPy中是可能的，而不仅仅是像其他人那样误用调试器API。不过，您必须修改字节码。

我认为while循环是“goto_Statement”的替代。因为3.6之后，goto循环不再工作了。我还写了一个while循环的例子。

str1 = "stop"
while str1 == "back":
    var1 = int(input(" Enter Ist Number: "))
    var2 = int(input(" Enter 2nd Number: "))
    var3 = print("""  What is your next operation
                      For Addition   Press And Enter : 'A'
                      For Muliplt    Press And Enter : 'M'
                      For Division   Press And Enter : 'D'
                      For Subtaction Press And Enter : 'S' """)

    var4 = str(input("For operation press any number : "))
    if(var1 == 45) and (var2 == 3):
        print("555")
    elif(var1 == 56) and (var2 == 9):
        print("77")
    elif(var1 == 56) and (var2 == 6):
        print("4")
    else:
        if(var4 == "A" or "a"):
            print(var1 + var2)
        if(var4 == "M" or "m"):
            print(var1 * var2)
        if(var4 == "D" or "d"):
            print(var1 / var2)
        if(var4 == "S" or "s"):
            print(var1 - var2)

    print("if you want to continue then type  'stop'")

    str1 = input()
print("Strt again")    

你可以使用python中的嵌套方法来实现

def func1():
    print("inside func1")
    def inline():
        print("im inside")
    
    inline()
    
func1()

现在有了。转到
