Why is my Placeholder not showing on my Tkinter Entry?-CodePudding

I am working on an Entry, or Input if you please, in Python using a Library called tkinter

This is the code I have used:

entryvar = Entry(name).pack()
entryvar.insert(0,'Enter')

But when I run the code, I get the following error:

AttributeError: 'NoneType' object has no attribute 'insert'

I am not sure why this is happening as i carefully followed a tutorial on this.

I have tried switching the single inverted commas to double inverted commas and then back, but that didn't work. If you have any suggestions, It would help. Thanks!

You are getting this error because you wrote entryvar = Entry(name).pack(). . .pack() returns as None so you should write:

entryvar = Entry(name)
entryvar.pack()
entryvar.insert(0,'Enter')

CodePudding user response：

The geometry manager methods (pack, place, and grid) all return None, so entryvar = Entry(name).pack() evaluates to None! Always declare your widgets, then pack() them separately for this reason.

Do this instead:

entryvar = Entry(name)
entryvar.pack()
entryvar.insert(0,'Enter')
