10. INTRODUCTION PYTHON PART TWO
11. VARIABLES SPREMENLJIVKE
12. BOOLEAN a = True b = False BOOLEAN
13. NUMBERS a = 10 b = 10.2 INTEGER FLOAT
14. STRINGS a = “niz znakov” INTEGER
15. OPERATORS ARITHMETIC
16. MATH OPERATIONS + - * / % **
17. STRINGS NIZI ZNAKOV
18. STRINGS a = “char \”escaping\” too” znak = “cats”[0] CHAR ESCAPE INDEXING
19. “test”.lower() STRING FUNCTIONS “test”.upper() LOWERCASE UPPERCASE len(“test”) LENGTH
20. TRICKS VARIOUS
21. COMMENTS # comment 1 “”” comment 1 comment 2 “”” SINGLE LINE MULTI LINE
22. print “text” PRINTING print a STRING VARIABLE print “a” + “b” CONCATENATION
23. “3”.int() TYPE CASTING str(3) STRING TO INT INT TO STRING
24. INTRODUCTION PYTHON PART THREE

26. == != < > <= >= COMPARATORS
27. and or not BOOLEAN OPERATORS not and or PRIORITY
28. if x < 9: print “st. x je manjse od 9” elif x > 9: print “st. x je vecje od 9” else: print “st. x je enako 9” CONDITIONAL STATEMENTS
