Okay for this script we're going
0:02
to create a text replacer.
0:04
So this is a quick script that will take in,
0:07
off the clipboard, some text,
0:10
and will allow you to then substitute
0:12
certain words in that text with other words,
0:16
and then paste it back to the clipboard.
0:19
Again, this is something I've used and I keep handy,
0:22
because there's a few times,
0:24
especially at work that I need to do stuff like this.
0:26
So let's import pyperclip.
0:33
Let's throw in this as usual.
0:38
Let's create our functions first.
0:41
We need to create a function
0:42
that will paste in the information, right?
0:45
So paste_from_clipboard.
0:47
I'm making these very detailed names,
0:50
just so we know what we're talking about.
0:52
And we'll say the text
0:55
that we're going to deal with is pyperclip.paste
1:00
And we'll return that.
1:03
So, return text.
1:06
I'm keeping this super clean and simple.
1:09
So we've got our text, we've read it in from the clipboard,
1:12
and we're going to return it.
1:16
Now we need to take that text,
1:19
and replace it.
1:22
We're going to do that with a replace_text.
1:26
So def replace_text.
1:30
Let's read in old text.
1:32
We'll just change the name like that
1:34
to make it interesting and descriptive.
1:38
Now what do we want to do?
1:39
We want to replace some text,
1:42
so we're going to ask the user what they would like to replace,
1:45
rather than hard code it in.
1:47
So we'll just create a target, is input:
1:52
What would you like to replace?
1:58
Then we're going to actually do the:
2:01
What do they want to replace it with?
2:04
First, they're specifying the word
2:06
they would like to have replaced,
2:07
and now they're saying what they want
2:09
to have it replaced with.
2:11
So replacement = input,
2:16
and what would you like to replace it with?
2:25
Let's just hit enter.
2:26
There we go.
2:33
We're going to build a new text block
2:36
after we've done the replacement.
2:38
To do that, we're going to go new text is...
2:41
So old text.replace,
2:45
cause we can do that.
2:47
It's Python, it's cool!
2:49
Old text.replace target,
2:53
and replacement,
2:55
and that just does a simple search for the target,
2:58
and then replaces it with the replacement text.
3:03
Then we'll return that.
3:04
Return new text.
3:08
Let's call these down here,
3:09
so first we're going to say old text,
3:14
cause remember we're calling that in here?
3:16
Old text is...
3:21
paste_from_clipboard,
3:27
and then new text
3:31
is replace text
3:36
and loading in the old text.
3:40
And now we need to copy it back.
3:44
It's going to be similar to the paste_from_clipboard,
3:46
we're going to def copy_to_clipboard.
3:52
And we'll load the new text into that.
3:56
And then all it needs to do is run that same pyperclip.
4:01
pyperclip.copy
4:04
New text.
4:06
Now obviously, this is a simple enough script,
4:08
you don't actually have to break it down into functions.
4:12
I just thought that'd be much easier
4:13
for displaying that.
4:16
Then we'll just print a little message saying,
4:19
the new string is now copied to the clipboard.
4:27
That's it.
4:31
So we'll get rid of the bright, white space.
4:33
Let's call that function here, okay?
4:36
And we go copy to clipboard
4:40
New text.
4:44
So we'll save that.
4:47
Let me just copy a block of text for us to actually do this.
4:52
We will do this.
4:57
So here's the block of text, alright?
5:03
Let's run the script.
5:07
Alright, what would you like to replace?
5:08
Let's replace Julien.
5:12
And what would you like to replace it with?
5:14
Bob.
5:16
The new string is copied to the clipboard.
5:19
What's cooler than cool?
5:20
Bob.
5:21
Now that's a blatant lie,
5:22
but that's a great demonstration point.
5:26
Let's try it again.
5:27
So we'll go run the script.
5:31
What would you like to replace?
5:32
Let's replace Bob with Mike.
5:37
New string is copied, let's hit paste.
5:39
What's cooler than cool?
5:41
Mike.
5:44
I'm not going to comment.
5:46
Sorry, Mike.
5:49
Let's run it one more time.
5:52
What would you like to replace?
5:54
Let's replace Mike with ice cold.
6:00
And paste. What's cooler than cool?
6:02
Ice cold.
6:03
And that's it.
6:04
Really cool, simple script.
6:05
Something usable, I'm sure it's something
6:07
you can make use of in day-to-day life.
6:10
Enjoy it, use it, and that's pretty's much...
