There is a syntax error and only add regex to match language constructs. No generic regex like credit card number.

@B-R-P I have made some changes to the file, will you please have a look at it

Format is not correct.
Most of regex are unnecessary for this program.
Only add regexs to match language constucts

@B-R-P This time, I added regexs to match language constructs only, using the above examples of the file, have a look at it.

Hello @Aditi840 make sure your function is error free, for the tests to pass smoothly.
This is the problem:

It looks like you're encountering a TypeError and a SystemExit exception in your Python code.

1.This error is happening in the replace_variables function, specifically in this line :

source_string = source_string.replace(f"<{variable_name}>", variable_value)

It seems like variable_value is expected to be a string, but it's a dictionary. You should check where variable_value is being assigned and make sure it contains a string.

2. The SystemExit exception is raised in your sys_exit() function, which is called from the extract function:

File "/home/runner/work/LangTrans/LangTrans/LangTrans.py", line 410, in extract
sys_exit()
This suggests that something in your code is calling sys_exit(), which is causing the program to exit unexpectedly. You should investigate why this function is being called and under what conditions.

Thank you. I will check it out

@B-R-P, I removed them, will you now run the test again.

This line is incorrect. Why expression as main node of other regexs?

Please try LangTrans first, then add relevant regular expressions

@B-R-P, will do
