Grouping Tkinter entry widgets and creating a for loop-CodePudding

I'm new to Tkinter and just wondering if there is anyway I could group some entry boxes like in a list and then do a for loop on them.

I'm watching this tutorial video and on clicking a button they want the button to clear all the entry boxes and they've done it like this:

# Create Submit fn for database
def submit():
    f_name.delete(0, END)
    l_name.delete(0, END)
    address.delete(0, END)
    city.delete(0, END)
    postcode.delete(0, END)

# Create entry textboxes
f_name = ttk.Entry(mainframe, width=30).grid(column=1, row=0)
l_name = ttk.Entry(mainframe, width=30).grid(column=1, row=1)
address = ttk.Entry(mainframe, width=30).grid(column=1, row=2)
city = ttk.Entry(mainframe, width=30).grid(column=1, row=3)
postcode = ttk.Entry(mainframe, width=30).grid(column=1, row=4)

# Create submit button
submit_btn = ttk.Button(mainframe, text="Add Record", width=20, command=submit).grid(column=0, row=6, pady=10)

Instead of the submit function being repetitive I would like to do something like this:

def submit():

entries = ttk.Entry(mainframe)

for entry in entries:
    entry.delete(0, END)

That function immediately above doesn't work but I'm looking for something along those lines to avoid the unneccessary repetition and have cleaner code. Is this possible?

CodePudding user response：

Widgets are objects, and objects can be added to a list. You do it no differently than you do strings or integers or any other type of object.

f_name = ttk.Entry(mainframe, width=30)
l_name = ttk.Entry(mainframe, width=30)
address = ttk.Entry(mainframe, width=30)
city = ttk.Entry(mainframe, width=30)
postcode = ttk.Entry(mainframe, width=30)

f_name.grid(column=1, row=0)
l_name.grid(column=1, row=1)
address.grid(column=1, row=2)
city.grid(column=1, row=3)
postcode.grid(column=1, row=4)

entries = [f_name, l_name, address, city, postcode]
...
for entry in entries:
    entry.delete(0, END)

You can also use a dictionary instead of individual variables. You can then iterate over the dictionary like you do any other dictionary:

entries = {
    "f_name": ttk.Entry(...),
    "l_name": ttk.Entry(....),
    ...
}
