我对python很陌生，并且遇到属性错误。

我在这里导入此类：
class FileHandeling:
def createFile(fo,numOfRecords,data,counterFile):
#Getting the value of counter
frc = open(counterFile,"r");
counter = int(frc.read());
frc.close();
#Taking input and writing to the file
for i in range(counter,numOfRecords+counter):
string = str(i)+data[i];
fo.write(string);
counter += 1;
#Writing back to counter the updated value.
fwc = open(counterFile,"w");
fwc.write(str(counter)+"\n");
fwc.close();
def readFile(fo,searchStr,criteria):
line = fo.readline();
string = [];
while line:
entries = line.split();
if(searchStr == entries[criteria]):
string.append(line);
line = fo.readline();
return string;
def printFile(fo):
fo.seek(0);
lines = fo.readlines();
print "The File: "
for line in lines:
print line;
def updateRecord(fo,fileLoc,updateStr,lineNum):
#Replacing the given record with he updated record and writing back to file
lines = fo.readlines();
fwu = open(fileLoc, "w");
lines[lineNum]= updateStr;
for line in lines:
fwu.write(line);
fwu.close();
def deleteRecord(fo,fileLoc,lineNum):
#Deleting the record
lines = fo.readlines();
fwu = open(fileLoc, "w");
lines.pop(lineNum);
#Correcting the Employee Ids and Writing Back to File
for line in lines:
entry1, entry2, entry3, entry4, entry5 = line.split();
entry1 = str(lines.index(line));
line = entry1+" "+entry2+" "+entry3+" "+entry4+" "+entry5+"\n";
fwu.write(line);
fwu.close();
#Reducing Counter value
frc = open(counterFile,"r");
counter = int(frc.read());
frc.close();
fwc = open(counterFile,"w");
fwc.write(str(counter-1)+"\n");
fwc.close();
在这段代码中，我试图在文件的帮助下复制数据库，但是我的代码给出了错误提示'module' object has no attribute 'createFile'。我还尝试创建包并像在Java中那样进行操作，但随后它开始说ImportError: No module named src.fileManipulation。它们只是我正在工作的文件夹，并希望将它们作为软件包，因此我在其中放入了__init__.py，而教程说这将有助于制作软件包，但这没有发生，因为我的两个文件都在same directory我直接导入了它，但是现在它给出了属性错误，我不知道这意味着什么。请帮忙。
答案 0 :(得分：0)
在更正了一些打印语句后，我已经在Python默认IDLE中执行了代码。我正在使用Python3，因此使用了print（“”）。结果是一个不断循环的
Wrong Choice!!!
Press:
1 to enter a new employee
2 to search employee
3 to update employee
4 to delete employee
0 to exit
我对您的要求是再次修改Python。
