Python Learning: Regular expression functions in Python the difference between match and search ()

1. Match function
   

Binary_re= ' [01]* ' pattern = re.compile (binary_re) m=re.match (binary_re,deststr) if M:print m.group (0) Else:print ' not Match

The match function is matched from the start of the string, the match fails to return none, the match succeeds,

M.group (0) matches the result of the 2.search function binary_re= ' [01]* ' pattern = re.compile (binary_re) m=re.search (BINARY_RE,DESTSTR) if M: Print M.group (0) else:print ' not match '

The search function scans the entire string and returns the first successful match
