Error

TypeError: argument of type 'method' is not iterable

code

some part of code, initialisation and all

while 1:
    q = variable1.get
    if "3202" in q:
        variable2.set("NI NODE3202")
        try:
            switch(labelframe2, labelframe1)
        except:
            switch(labelframe3, labelframe1)
    elif "3212" in q:
        variable2.set("NI NODE3212")
        try:
            switch(labelframe1, labelframe2)
        except:
            switch(labelframe3, labelframe2)
    elif "3214" in q:
        variable2.set("NI NODE3214")
        try:
            switch(labelframe1, labelframe3)
        except:
            switch(labelframe2, labelframe3)
    else:
        None

some other part of code

def switch(x, y):

    if x.isGridded:
        x.isGridded = False
        x.grid_forget()
        y.isGridded = True
        y.grid(row=0, column=0)
    else: 
        return False

I am trying to create a switch between three labelframes which are inside another labelframe, and outside this labelframe are other labelframes that are not changing.

I have read some similar answers but I don't want to use __iter__() in my code. Can anybody provide any other suggestions?

Answer 1

You forgot to call the Entry.get() method:

q = variable1.get()
#                ^^ call the method

Because the method object itself doesn't support containment testing directly, Python is instead trying to iterate over the object to see if there are any elements contained in it that match your string.

If you call the method, you get a string value instead. Strings do support containment testing.

Answer 2

The reason you got that error was because you did not add "()" after.get query hence the error to fix this change q = variable1.get to q = variable.get()
