Python Struct.unpack_python

1. Set the Fomat format as follows:

Copy Code code as follows:

# take the first 5 characters, skip the 4-character Fu Hua, and then take 3 characters
format = ' 5s 4x 3s '

2. Using Struck.unpack to get the substring

Copy Code code as follows:

Import struct
Print struct.unpack (format, ' Test astring ')
# (' Test ', ' ing ')

For a simple example, there is a string ' He isn't very happy ', handle it, remove the middle not, and then output.

Copy Code code as follows:

Import struct
TheString = ' He's not very happy '
format = ' 2s 1x 2s 5x 4s 1x 5s '
print '. Join (Struct.unpack (format, thestring))

Output results:
He is very happy
