Hello,
I would like to know how possible it is to call a member function from a class
and pass it a variable
Example:
class Application(tk.Frame):
"""docstring for ."""
def __init__(self, parent):
super(Application, self).__init__(parent)
self.parent = parent
parent.title('Courses selections')
#parent.geometry("700x350")
parent.geometry('500x320+0+0') #Width x Height
# Create widgets/grid
self.create_widgets()
self.selected_item = 0
def create_widgets(self):
### FIRST NAME LABEL + ENTRY
self.firstName_txt = tk.StringVar()
self.firstName_lbl = tk.Label(self.parent, text='First Name',
font=('bold'))
self.firstName_lbl.place(x=20,y=10)
self.firstName_entry = tk.Entry(self.parent,
textvariable=self.firstName_txt)
self.firstName_entry.place(x=120,y=10)
...
def prereq(self):
self.boo = 1
if self.firstName_txt.get() == "":
msg.showwarning("Missing information", "First name info missing")
boo = 0
elif self.lastName_txt.get() == "":
msg.showwarning("Missing information", "Last name info missing")
boo = 0
elif self.age_txt.get() == "":
msg.showwarning("Missing information", "Age info missing")
boo = 0
elif self.rBtnGender.get() == 0:
msg.showwarning("Missing information", "Gender info missing")
boo = 0
if self.boo == 1:
self.fname = self.firstName_txt.get()
self.lname = self.lastName_txt.get()
self.age = int(self.age_txt.get())
self.selectedCourse =
self.coursesLBX.get(self.coursesLBX.curselection())
if self.age < 21:
msg.showwarning("Invalid Age", "Invalid Age, you are not
eligible")
return
elif self.age >= 21:
pass
### SELECTED COURSE
if self.selectedCourse == "Quality Management (Adv.)":
self.prereq = "The prereq for this course is Quality Management
(Int)."
self.flag = 1
elif self.selectedCourse == "Financial Management (Adv.)":
self.prereq = "The prereq for this course is Financial
Management (Bas)."
self.flag= 1
elif self.selectedCourse == "Project Management (Adv.)":
self.prereq = "The prereq for this course is Project Management
(Int)."
self.flag = 0
else:
self.prereq = "The prereq for this course is Project Management
(Bas)."
self.flag = 0
### PART TIME
if self.chkBtnPTime.get() == 1 and self.flag == 0:
self.str2 = "\nThis course is not available part time."
elif self.chkBtnPTime.get() == 1 and self.flag == 1:
self.str2 = "\nThis course is available part time."
else:
self.str2 = ""
self.result = self.prereq + self.str2
msg.showinfo('Form info', self.result)
def save2db(self):
try:
db.insert(self.fname, self.lname, self.age)
msg.showinfo('DB action', "Selection inserted into db")
except:
msg.showinfo("Form submission failed", "Plz check ur input")

In function save2db, I would like to know if there is any alternative to using
try/except. The alternative I'm thinking is something like
def save2db(self,boo):
if boo == 1:
do something
else:
do something like return to previous step...
Is this possible?
