Question

我已经在这个Python程序上工作了几周，终于在Ubuntu Bionic上使其工作了。他们必须具有较旧的Python版本，因为在Arch Linux的Reborn OS上，该程序将无法运行。它得到语法错误。 Ubuntu上的一个是2.7.15，而Reborn OS上的是3.6.6。我收到以下错误：

[caden@Reborn ~]$ python ~/Dropbox/kodebyter/kodebyter.py 
  File "/home/caden/Dropbox/kodebyter/kodebyter.py", line 34
    print str(rotation)
            ^
SyntaxError: invalid syntax

我的脚本是这样的：

import string
import collections


def caesar(rotate_string, number_to_rotate_by):

    upper = collections.deque(string.ascii_uppercase)
    lower = collections.deque(string.ascii_lowercase)

    upper.rotate(number_to_rotate_by)
    lower.rotate(number_to_rotate_by)

    upper = ''.join(list(upper))
    lower = ''.join(list(lower))

    return rotate_string.translate(string.maketrans(string.ascii_uppercase, upper)).translate(string.maketrans(string.ascii_lowercase, lower))

print("Welcome to Kode Byter!")

print("Press Ctrl+C at any time to exit")

print("Press Ctrl+Shift+C to copy")

print("Press Ctrl+Shift+V to paste")

print("Will exit in 5")

print("Enter message:")
message = raw_input()

print("Enter rotation:")
rotation = raw_input()

print str(rotation)
print caesar(message, int(rotation))

print("Will exit in 4")

print("Enter message:")
message = raw_input()

print("Enter rotation:")
rotation = raw_input()

print str(rotation)
print caesar(message, int(rotation))

print("Will exit in 3")

print("Enter message:")
message = raw_input()

print("Enter rotation:")
rotation = raw_input()

print str(rotation)
print caesar(message, int(rotation))

print("Will exit in 2")

print("Enter message:")
message = raw_input()

print("Enter rotation:")
rotation = raw_input()

print str(rotation)
print caesar(message, int(rotation))

print("Will exit in 1")

print("Enter message:")
message = raw_input()

print("Enter rotation:")
rotation = raw_input()

print str(rotation)
print caesar(message, int(rotation))

print("Will exit in 0")

print("Press enter to exit...")
exit = raw_input()

我需要使用它来处理Arch Linux，因为我将其制作成Arch Linux软件包，以便用户从pacman安装。
