Answer 1

Saeed Mozaffari Convert your regex pattern to a raw string as r'len(daught)er)'.

Also, you should close the file to avoid leaks using `fh.close()` on line 10.

Answer 2

try your code on pc because there is no Emma.txt file in your android if it is exist in your device then you can't call here because you can only import such these directories only on pc not android.

Answer 3

Saeed Mozaffari try this code hope it will help you. but try on computer not android and file should be exist in your computer Emma.txt

Answer 7

Emerson Prado Yes, in SoloLearn and i watched a tutorial video about regular expression in my own language.

Answer 8

Where is file "Emma.txt"?

Answer 9

Emerson Prado Where above code there is. In a folder named 'regular expression'. i save that file in a nodepad in my pc.

Answer 10

Saeed Mozaffari OK. Which are the file contents?

Answer 11

Maninder Singh On my pc it gives no output.

Answer 12

Emerson Prado 'Emma'

Answer 13

Saeed Mozaffari If your file only contains 'Emma' and you're trying to match for 'len(daught)er', it simply doesn't match, so you won't get any output. Populate your file with content that can match.
Did you study the RegEx classes?

Answer 14

Emerson Prado Excuse me, in regular expression re.search find and show an specific character from the file????

Answer 15

Saeed Mozaffari Not a specific character, but the string that matched the expression. For an example, 'len(daught)er' would match 'lendaughtet' and return 'daught'.
