Multiple regex pattern

time = re.search(r'\d\d:\d\d:\d\d' , f.read().decode('utf-16'))
print time.group()

and

number = re.search(r'[TEL:+]\d+\n', f.read().decode('utf-16'))
print number.group()

both code works fine individually , but when I try to run in single script like this :

number = re.search(r'[TEL:+]\d+\n', f.read().decode('utf-16'))
print number.group()

time = re.search(r'\d\d:\d\d:\d\d' , f.read().decode('utf-16'))
print time.group()

second pattern didn't worked . 

print time.group()
AttributeError: 'NoneType' object has no attribute 'group'

Any idea what I am missing here ?

This is because the first read() consumes the whole file.

You should reset the pointer after the first read() as follows:

number = re.search(r'[TEL:+]\d+\n', f.read().decode('utf-16'))
print number.group()

f.seek(0,0)

time = re.search(r'\d\d:\d\d:\d\d' , f.read().decode('utf-16'))
print time.group()
