Question

我已经编写了下面的Python代码，并试图通过从python shell导入它作为模块，但它的抛出错误。

def break_words(stuff):

"""This function will break up words fro us."""
    words = stuff.split('')
    return words

def sort_words(words):
"""sort the words."""
    return sorted(words)

def print_first_word(words):
 """Prints the first word after popping it off."""
    word=words.pop(0)
    print word

def print_last_word(words):
"""print the last word after poppomg it off."""
    word=words.pop(-1)
    print word

def sort_sentence(sentence):
    """Takes a full sentence and return the sorted word."""
    words= break_words(sentence)
    return sort_words(words)

def print_first_and_last(sentence):
    """Prints the first and last word of the sentences."""
    words = sort_sentence(sentence)
    print_first_word(words)
    print_last_word(words)

当我从python shell导入它时： -

>>> import Breaking_code

Traceback (most recent call last):
 File "<pyshell#4>", line 1, in <module>
    import Breaking_code
ImportError: No module named Breaking_code

我的目标是将其用作下面的模块

sentence = "All good things come to those who wait."
words = Breaking_code.break_words(sentence)
output:- ['All', 'good', 'things', 'come', 'to', 'those', 'who', 'wait.']

Answer 1

确定您已在某个目录中编写了一个要在shell中导入的模块。但是模块的范围仅限于模块所在的目录。要在shell中导入模块

有两个选项

1.在系统环境变量中添加模块所在的目录。您也可以通过代码执行此操作

import sys
sys.path.append("your\\ directory\\path here")
import breaking_code

2.只需快速更改目录

import os
os.chdir("your\\ directory\\path here") #changing current working directory
import breaking_code

Answer 2

Breaking_Code.py很可能不在Python shell所在的文件夹中。如果只是尝试使用

导入一个函数

来自breaking_code import sort_words

导入python脚本作为模块时出错
