I am new to python and have hit a wall. I followed several tutorials but cant get past the error:
Traceback (most recent call last):
File "C:\Users\Dom\Desktop\test\test.py", line 7, in <module>
p = Pump.getPumps()
TypeError: getPumps() missing 1 required positional argument: 'self'
I examined several tutorials but there doesn't seem to be anything different from my code. The only thing I can think of is that python 3.3 requires different syntax.
main scipt:
# test script
from lib.pump import Pump
print ("THIS IS A TEST OF PYTHON") # this prints
p = Pump.getPumps()
print (p)
Pump class:
import pymysql
class Pump:
def __init__(self):
print ("init") # never prints
def getPumps(self):
# Open database connection
# some stuff here that never gets executed because of error
If I understand correctly "self" is passed to the constructor and methods automatically. What am I doing wrong here?
I am using windows 8 with python 3.3.2
You need to instantiate a class instance here.
Use
p = Pump()
p.getPumps()
Small example -
>>> class TestClass:
def __init__(self):
print("in init")
def testFunc(self):
print("in Test Func")
>>> testInstance = TestClass()
in init
>>> testInstance.testFunc()
in Test Func
