@haribharadwaj Only a nitpick, if a line exceeds characters, we indent it such that the next line starts where the function call operator ends in the line before.  If the next line goes beyond 80 chars we do the same as wit line 1, and so forth. Installing a PEP8 plugin to your editor makes it easier to write consistent code.

This would be the style-consitent way:
```Python
temp = temp + re.findall('cardinal\s([\d,.]+)\s(-?[\d,.]+)\s(-?[\d,.]+)\s(-?
                         '[\d,.]+)', fid)
```
