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.

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

• abs , max , min
• math.ceil , math.floor , round,
• random functions lile : choice , shuffle , randrange , uniform

String Functions and string Operators:

• string operators like + , * , [] , [:] , in , not in

• validation functions like isalpha , isdigit , isalnum , isupper , islower

• practical implementations with files using lists.
• List operators + , * , [] , [:] , in , not in
• List fundtions like len , max , min
• append , extend , index , insert , pop
• deep copy and shallow copy

• map , reduce , filter

• tuple operators + , * , [] , [:] , in , not in
• difference between list and tuple
• tuple functions len , max , min , copy
• map , reduce , filter

• Difference between list and dictionary
• dictionary operators like [] , in , not in
• dictionary functions like len , keys , values , items ,
• get , fromkeys , setdefault

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.

Exception Handling: 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

• User defined exception
• assert statement
• 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

• difference between user defined and system defined functions
• types of user defined functions like
• Required and positional arguments
• required and nonpositional Keyword arguments
• default arguments
• Variable-length arguments

user-defined modules:

• import statement
• from statement
• difference between import and from statement
• importance of __init__.py file
• alias naming in python
• Importing one python script in another

ADVANCED CONCEPTS :
