fix bug and more

1. The code is optimized according to the PEP8 specification
2. Fix an error when the program accepts parameters
3. An API interface has been added to allow other programs to generate strings using the ‘generate(int length)’ function.
4. Optimize the generated dictionary
5. Optimizations reduce program space complexity
