不同 *.py 文件之间的交叉引用可能吗?

Cross referencing between different *.py files possible?

我的程序 tui.py 包含大约 70 个函数,它们按组分类到四个不同的文档中:

大多数函数至少调用一个其他函数,有些函数还调用另一个 *.py 文件中的函数。

我已经尝试将 __init__ 函数(如下所示)放入我的 "main" 文档 (tui.py) 并创建一个额外的主文档,其中我将 tui.__init__(不作为函数放在那里)。

tui.py

(部分,尽可能简单)

import shutil
import os
from tbt import *
from ens import *
from hmm import *

def window () :
    print ( '\n//======================================================\\' )
    print ( '||\t\t\t\t\t\t\t||' )
    print ( '||\t\t\t\t\t\t\t||' )
    print ( '||\tR E ad-in of saved variables from file(s) E\t||' )
    print ( '||\tDe L etion of saved files or created dirs L\t||' )
    print ( '||\tStart of computation  . . . . . . . . . . B\t||' )
    print ( '||\tShow this window . . . . . . . . . .  . . W\t||' )
    print ( '||\tExit program  . . . . . . . . . . . . . . Q\t||' )
    print ( '||\t\t\t\t\t\t\t||' )
    print ( '||\t\t\t\t\t\t\t||' )
    print ( '\\======================================================//\n' )

def erase (content) : # simplified version, to keep the code comprehensible
    shutil.rmtree (  os.path.join (pathname, filename) )
    return pathname, filename

def compute (content, hmm) : # here needs to be ens.py, hmm.py, tbt.py included.
    content, hmm = tbt_init (content, hmm)
    return content, hmm

def __init__ (self, content, hmm) :
    window ()
    give_in = input ( '\tWhat comes next? ' )

    while give_in != 'q' and give_in != 'Q' :
        if len (give_in) > 1 : # check wether exactly one command was put in.
            give_in = input ( 'Type and execute the commands one by one. ' )
        elif give_in == 'N' :
            give_in = input ( '\tAnd now? [Window with W.] ' )
        elif give_in == 'e' or give_in == 'E' :
            content, hmm = read_file (content, hmm)
            give_in = 'N'
        elif give_in == 'l' or give_in == 'L' :
            pathname, filename = erase (content)
            give_in = 'N'
        elif give_in == 'b' or give_in == 'B' :
            content, hmm = compute (content, hmm)
            give_in = 'N'
        elif give_in == 'w' or give_in == 'W' :
            window (verbose)
            give_in = 'N'
        else :
            give_in = input ( 'Unknown command. Exit program with Q. ' )
    if give_in == 'q' or give_in == 'Q' : # The if statement isn't really needed indeed, but it's there, just in case.
        quit ()
    quit () # This also isn't really needed indeed, but it's there, just in case.
    return content, hmm

tbt.py

def tbt_init (content, hmm) :
    # some other stuff
    os.mkdir (content ['path'])
    pathname, filename = erase (content) # this lies in tui.py
    return content, hmm

这个版本没有给我任何输出。

将所有四个文件都导入到每个其他文件中也无济于事。我还需要在每个子文件中导入 python 模块(osshutil),尽管它们已经导入到 tui.py

执行上面的代码有什么问题?它如何成为一个工作代码?

编辑: 我收到以下错误,具体取决于更改源文件中的三行:

原始形式的片段

# tui.py
from tbt import * 
content, hmm = tbt_init (content, hmm)
# tbt.py
## nothing imported here
pathname, filename = erase (content)

  File "tui.py", line 62, in <module>
    content, hmm = compute (content, hmm)
  File "tui.py", line 44, in compute
    content, hmm = tbt_init (content, hmm)
  File /home/user/tbt.py, line 5, in tbt_init
    pathname, filename = erase (content) # this lies in tui.py
NameError: name 'erase' is not defined

让 'erase' 被 'tbt.py'

发现
# tui.py
from tbt import * 
content, hmm = tbt_init (content, hmm)
# tbt.py
from tui import *
pathname, filename = erase (content)

  File "tui.py", line 5, in <module>
    from tbt import *
  File "/home/user/tbt.py", line 2, in <module>
    from tui import *

  File "/home/user/tui.py", line 44, in compute
    content, hmm = tbt_init (content, hmm)
NameError: name 'tbt_init' is not defined

制作绝对模块名称

# tui.py
import tbt
content, hmm = tbt.tbt_init (content, hmm)
# tbt.py
## nothing imported
pathname, filename = erase (content)

  File "tui.py", line 63, in <module>

  File "/home/user/tbt.py", line 5, in tbt_init
    pathname, filename = erase (content) # this lies in tui.py
NameError: name 'erase' is not defined

让 'erase' 被发现

# tui.py
import tbt
content, hmm = tbt.tbt_init (content, hmm)
# tbt.py
import tui
pathname, filename = tui.erase (content)

  File "tui.py", line 6, in <module>

尝试更改您的 __init__ 方法:
