在早期版本上运行的Python可执行文件

Question

可以说人1具有用Python 3.x编写的python可执行文件（mac）。 Person 1将所述文件发送给Person 2，Person 2也拥有一个mac，但只有Python 2.6.1。当Person 2运行该文件时，它会起作用吗？

有人说，他们需要看到的代码，所以：

#!/usr/bin/env python 
# -*- coding: UTF8 -*- 
topo1 = 0 
topo2 = 0 
print("This program helps compare two players: ") 
print("It only uses that player's stats from the previous two years to determine their worth in fantasy baseball") 
def complay1(): 
    global topo1 
    print("Enter in the first player's stats below") 
    homerun = input("Enter in the player's home run total from the most recent year: ") 
    sb = input("Enter in the player's stolen base total from the most recent year: ") 
    hit = input("Enter in the player's hit total from the most recent year: ") 
    walks = input("Enter in the player's walk total from the most recent year: ") 
    doubles = input("Enter in the player's doubles total from the most recent year: ") 
    rbi = input("Enter in the player's RBI total from the most recent year: ") 
    ba = input("Enter in the player's batting average from the most recent year, do not include a decimal point: ") 
    hitL = input("Enter in the player's hit total from the year before the most recent year: ") 
    homerunL = input("Enter in the player's home run total from the year before the most recent year: ") 
    age = input("Enter in the player's age: ") 
    gp = input("How many games did the player play last year?: ") 
    topo1 += int(homerun)*3 
    topo1 += int(sb)*2 
    topo1 += int(hit)/2.5 
    topo1 += int(walks)/4 
    topo1 += int(doubles) 
    topo1 += int(rbi)/3 
    topo1 += int(hitL)/15 
    topo1 += int(homerunL) 
    topo1/(int(gp)/4) 
    topo1 -= int(age) 
    topo1 += int(ba)/2 
    print(topo1, "is the total PLV+ for this player") 
def complay2(): 
    global topo2 
    print("Enter in the second player's stats below") 
    homerun = input("Enter in the player's home run total from the most recent year: ")

    topo2 += int(homerun)*3 
    topo2 += int(sb)*2

    topo2/(int(gp)/4) 
    topo2 -= int(age) 
    topo1 += int(ba)/2 
    print(topo2, "is the total PLV+ for this player")  
complay1()  
complay2() 
if topo1 > topo2: 
    print("Player 1 is", ((topo1/topo2)*100)-100, "percent better") 
if topo2 > topo1: 
    print("Player 2 is", ((topo2/topo1)*100)-100, "percent better") 

Answer 1

大概不会，主版本的变化没有向后兼容性。

编辑：对于您的代码示例，它可能有效。脚本中2和3之间唯一改变的是print 2不是Python 2中的函数，这是不重要的，因为print（x）与Python 2解释器的print x相同，额外的括号不会造成伤害。

EDIT2：正如在不同的答案中所说，该部门也将打破。这是因为int/int将导致Python 2中的int和Python 3中的float。这意味着5/2在Python 2中为2，在Python 3中为2.5。from __future__ import division解决了此问题。

Answer 2

这是不可能的完全一定没有看到代码，但也出现了2.x和3.x之间变化的很多，使它非常不可能奏效。

编辑：

该部门将打破它。将from __future__ import division放在顶部。另外，检查是否存在raw_input，将其分配给input。

Answer 3

可执行文件是什么意思？我对python可执行文件的想法是将python捆绑在其中，所以最终用户不需要安装python来运行它。

如果你的意思只是.py，看着你发布的代码，它看起来是兼容的。
