ImportError: cannot import the class

[nischalinn]

I can not figure out what mistake I've done with my code. The error indicates that the class can not be imported. But I am not getting into it.

Please help me with this.

My code:

######## userClass.py ##################
from classTriangle import classTriangle

class userClass():
    
    def __init__(self):
        self.getList = []
        self.maxList = 3
        
    
    def getUserList(self):
        print("*** getting user input ***")
        while len(self.getList) < self.maxList:
            item = input("enter numbers: ")
            self.getList.append(item)
        return self.getList    
        
    def showUserList(self,passedList):
        print("*** showing user input ***")
        print (passedList)
        print ("length of the list: ", len(passedList))
        
        
if __name__=='__main__':
    ui = userClass()
    mk = classTriangle()
    displayList = ui.getUserList()
    ui.showUserList(displayList)    
    print(mk.createTriangle())
           
        
########classTriangle.py############
from userClass import userClass 

class classTriangle(): 
        
    def __init__(self):
        self.makeList = []
        self.bridgeList = []
        self.finalList = []   
    
    def createTriangle(self):
        UI = userClass()
        self.makeList = UI.getUserList()
        while len(self.makeList)>1:
            for i in range(len(self.makeList)):
                j = i + (i+1)
                self.bridgeList.append(j)
            del self.makeList[:]
            self.makeList.extend(self.bridgeList)  
            self.finalList.extend(self.bridgeList)
            del self.bridgeList[:]
        return self.finalList

The error shown is:

ImportError: cannot import name 'userClass'

Please help.

from userClass import userClass
ImportError: cannot import name 'userClass'

Because both the file and the class have the same name, there is no way to tell if the problem is with the program named userClass.py or the class named userClass within the userClass.py program. For starters see if the program is in the PYTHONPATH, i.e. your program can find this program, by inserting this

if os.path.isfile("userClass.py"):
    import userClass.py
else:
    ## whatever you want

See the Search Path here for info on expanding the search path on a per program basis. On a Linux system you can add an additional new path(s) to the PYTHONPATH variable in your ~.bashrc file.

@dwblas:

Thanks for your help. I've read the post. I've created a new class called "main" and have instantiate all the classes there.

Thank You!!!
