Prerequisistes: Python GUI – tkinter
Firstly we need to find all the words or letters that we want to replace in our below text for that we will use the find function in which we will determine all the starting and the ending indexes from the editor of the same word after that we will apply the replace functionality in which we will delete that part of the text and after that, we will apply insert function to add the text at that exact positions.
Important inbuilt functions used
- Tk() it creates a base window/tkinter base widget
- Frame() it creates a a separate Frame at a particular position on the Tk() instance
- Label() it adds the statement or the name or labeling of anything
- Entry() it adds the dialog box to enter the text
- ‘EntryInstance’ .pack() it packs the entry box at the specified position
- Button() it places a button at the specifed position with the command and the label
- Text() it places a text Box to write ans add content
- ‘TextInstance’ .insert() it adds text at the specified index(over here index is of string type)
- ‘TextInstance’ .tag_add() Tags are used to refer to all the contents at the same time, for eg if a paragraph contains text “this” five times and in order to make a change to them at all at same time we use tags. tag_Add adds all those text under a particular tag where name is provided by us
- ‘TextInstance’ .tag_config() they are used to configure them that is highlight, font, background color, foreground color
- ‘TextInstance’ .tag_remove() used to remove all the text used from starting index to ending index
- ‘EntryInstance’ .get() used to have access to the text entered inside the dialog box of Entry
- ‘TextInstance’ .search() used to search a particular text in the whole editor from starting index till end with an argument of ‘nocase’ which if set 1 implies no case sensitivity will be considered in search
- ‘ButtonInstance’ .config() used to confiure the button that is we can separately add the command or the changes in the button that will take place when it will be pressed
- ‘TkInstance’ .mainloop() used to make sure that the text widget remain open
Below is the implementation.
