PYTHON DATA TYPES AND SYSTEM DEFINED FUNCTIONS:

This section of python comprises of the system related concepts like data types, system-defined functions with practical implementations. System Module concept. how to import the system defined modules and its uses.

• Python Data types like Numbers , Strings , Lists , Tuples , Dictionaries etc
• difference between Normal and module function eg math , random.

数字功能：The functions which works on the number inputs are number functions. This section also comprise system defined number functions .

• abs , max , min

USER-DEFINED CONCEPTS :

In the above section 2, we seen every function or module used is system defined. This section mainly focuses on user-defined elements like user-defined functions, types of user-defined functions and its importance. Return statement. user-defined modules how can user-defined modules are imported etc.

异常处理：This section consists of handilng the exceptions using try and except block. Importance of the word Exception and system defined exceptions. User defined exceptions its importance. assert statement.

• try , except block

• finally block

• file handlers
• file functions like open , read , readline , readlines , write , writeline , writelines , close , seek , tell
• file modes like r, w, a, r+, w+, a+, rb, wb, ab
