11. Python is a general purpose, high level language. 
 It is dynamically typed and interpreted language
12. Printing print(“Hello World!”) print(var)
13. Reading Input a=input() a=“type”
14. Combining IO print(‘%s%d’%(var1,var2))
15. Comments #
16. Names, Types number = 3214 string = “Hello World !” bool = True
17. Conditionals Keywords if, elif ,else if condition: …… else: …… elif condition: ……
18. Conditionals PIT HOLE: Don’t forget to add ‘:’ at the end of your conditional statement. Indentation is must.
19. Math Operators +, - ,*, **, /, %, << , >>, &, |, ^, < >, <=, >=, ==, != ** The Beautiful Math Library is also your Treasure
20. Compound Data Types list = [23,24,1,2,34,4] # Collections, Arrays in Other Languages dictionary = {1:”hello”,2:”bye”} # Key Value Pairs tuples = () # Locked Sequences file = open(‘name.ext’,’m’) # Takes in File into file Variable
21. Iterators for, while
22. for VAR in LIST
23. For Loop for VAR in COLLECTION: l = [23,43,12,32,2] for i in l: print i d = {‘EK4’:’ECE’,’EK5’:’CSE’} for i in d: print d[key] t = (22,32) for i in t: print i file = open(‘names.txt’,’r’) for i in file print i
24. The Range Function range(start,end) range(0,50)
25. While while condition: while a<b: print a ……. …….
26. Iterators PIT HOLE: Don’t forget to add ‘:’ at the end of your iterative statement. Indentation is must after your iterative statement.
27. The for statement iterates through a collection The while statement simply loops until a condition is False Making it Clear !
28. Intermission
29. Slicing var[ : ] var[2:5] var[:-1] var[-2:]
30. Built Methods For Strings For Strings .strip() .spilt() .upper() .capitalize() .startswith() .swapcase() .islower()
31. Built Methods For Lists For Lists .sort() .append() .reverse() .insert() .index()
32. Built Methods For Dicts For Dicts .keys() .values() .items() .has_key()
33. Built Functions len() min() max() sum()
34. Solving Problems Age Calculator Activity Monitor Super Market Cleaning Election Data
35. Helping Functions dir() help() type()
36. print(“Questions”)
37. The End
