如何在Jupyter Notebook中通过交互式小部件（Python）定义变量名

Question

I need the following functionality:

#what do you want to name the processed file?
(widget here)

filename=(widget input string)

I did not find any easy examples in the widget documentation or other searches.

Answer 1

You can either use standard python input()

text = input("Your input: ")
print(text)

or use the ipywidgets module

import ipywidgets as widgets
text = widgets.Text(placeholder='Your input')
display(text)

def print_input(sender):
    print(text.value)

text.on_submit(print_input)

also see the docs for the ipywidgets module here .
