我在编写程序时遇到了大麻烦，我决定在不同的文件上创建程序，每个文件都有一个类，现在它给了我以下错误
File "principal.py", line 5, in <module>
import plotting.plot
File "/home/bojack/Dropbox/Maquina/obtencion/plotting/plot.py", line 1, in <module>
import matplotlib.pyplot as plt
File "/usr/lib/pymodules/python2.7/matplotlib/__init__.py", line 123, in <module>
import pyparsing
File "/usr/local/lib/python2.7/dist-packages/pyparsing-2.0.3-py2.7.egg/pyparsing.py", line 160, in <module>
alphas = string.ascii_lowercase + string.ascii_uppercase
AttributeError: 'module' object has no attribute 'ascii_lowercase'
文件在dir上如下
MyDir＆gt;＆gt; principal.py plot.py dxf.py linea.py string.py
如果我在不同的目录上运行plot.py文件，它运行完美，它只是在该目录上不起作用，所以我重新安装了一个子目录中的plot.py文件，添加了一个 init .py空白文件也是如上所述的子目录 Python Modules Contents现在我没有想法，任何人都能帮忙吗？
这是我的脚本代码

答案 0 :(得分：1)
您的文件夹中似乎有一个string.py文件，因此import string实际上会导入您的string.py因为它与内置模块的名称相同，所以会代替它。因此，我建议您更改文件名称classes.py，而不是from classes import String
此外，您为主程序创建了一个类，它不是在Python中创建入口点的方法。
那更好：
#!/usr/bin/env python
import dxf
import string
from classes import String
import linea
import plotting.plot
import matplotlib.pyplot
import numpy
import dxfgrabber
import getpass
import os
def main():
archivo=input('ingresa nombre del archivo : \n>>')
#instaciamos objetos
objdxf=dxf.Lectura(archivo)
stringg=String()
objdxf.Pdf2Dxf()
linea1=objdxf.getDxf()
lineas=linea.Lineas(linea1)
start,end=lineas.grabLinea()
startS=stringg.separar(start)
endS=stringg.separar(end)
startC=stringg.cortar(startS)
endC=stringg.cortar(endS)
plt=plot.Graph(startC,endC)
if __name__ == '__main__':
main()
另请注意，您只应在需要时导入，例如在主代码中使用import string但不使用它。
