</div>

region\_name = ‘test region’  
region\_checked= ‘ReplaceText’  
resp = region\_checked.replace(‘ReplaceText’,‘Region : region\_name’)  
print(resp)

Output I want to see is ‘Region : test region’

How can I get this output.

As you have written this line, region\_name is part of the string you are outputting. You want the content concatenated to the first part of the string:

```py3
>>> region_name = 'test region'
>>> region_checked= 'ReplaceText'
>>> region_checked.replace('ReplaceText','Region : '+ region_name)
'Region : test region'

```

If it is just about the text output, there are more ways to do what you, e.g. through string formatting:

```auto
>>> 'Region : {}'.format(region_name)
'Region : test region'

```

See [string — Common string operations — Python 3.12.1 documentation](https://docs.python.org/3/library/string.html#format-string-syntax) and the [formatted string literals](https://docs.python.org/3/reference/lexical_analysis.html#formatted-string-literals).
