Good morning I have problem when i go to use string.replace() in my script where string is a multiline text.

I don’t receive any error , script arrive to the end, but replace don’t be do it.

here a piece of code :

text = event.source.parent.getComponent(‘lblprintBase’).text

```
value = event.source.parent.getComponent('ptProd').QR
text.replace('@QR', value)

value = event.source.parent.getComponent('ptProd').Line1
text.replace("@LINE1", value)

value = event.source.parent.getComponent('ptProd').Line2
text.replace("@LINE2", value)

value = event.source.parent.getComponent('ptProd').Line3
text.replace("@LINE3", value)

value = event.source.parent.getComponent('ptProd').Line4
text.replace("@LINE4", value)

value = event.source.parent.getComponent('ptProd').Line5
text.replace("@LINE5", value)

event.source.parent.getComponent('lblprintMod').text= text

```

Some ideas ?

Thanks

See some documentation: [Python String replace() Method](https://www.tutorialspoint.com/python/string_replace.htm)

> Python string method **replace()** returns a copy of the string...

So you need to reassign your text:

```auto
text = text.replace("@QR", value)

```
