#         how to modify a string by
#         converting it to an array
#-----------------------------------------
import array
str = 'My name is Kevin'
print( 'str = ' + str )
# We're not allowed to modify strings 
# so we'll need to convert it to a
# character array instead...
charArray    = array.array( 'B', str )
# assignment
charArray[11:16] = array.array( 'B', 'Jason' )
# replacement
str = charArray.tostring()
# assignment back to the string object
print( 'str = ' + str )
input( '\n\nPress Enter to exit...' )

输出结果：

str = My name is Kevin
str = My name is Jason
 
Press Enter to exit...
