Print(10 9) print(10 == 9) print (10 9) Boolean Print(bool("hello")) print(bool("15")) print(bool(x)) Boolean examples of true Print(bool(false)) print( ) print(0) Boolean examples of false Print(isinstance(x, int)) Determine if an object is of a certain data type Int( ) Casts an integer from an integer literal, float literal, or string literal Float( ) Casts a float from an integer literal, a float literal, or a string literal Str( ) Casts a string from strings, integer literals, or a float literals Print("text") Outputs text to the console Print("text", end=" ") print("more text") Will end with a space and continue on the same line ("text more text") Print("wage", wage) Comma will print both items with a space between them Print(variable) Prints the value of the variable Print("1n2n3") Print using newline characters Print( ) Print a blank line Python Run a script file Random function WGU WGU There is no random function, but there is a random module (import random) For x in "bananas": print(x) Strings are arrays, so this will loop through the characters in "bananas" Variable=input( ) Assign text entered by the user to a variable; input is always a string Variable = int(input) Convert user input into an integer Hourly_wage = int(input("enter hourly wage: ")) Display text prompt (enter hourly wage) to request input from user and convert to integer Print(( )) Display a in console in upper case Print(( )) Display a in console as lower case Print(( )) Remove whitespace at beginning and end Print(ce("h", "j")) Replace a string with another string Print(("b")) Split string at specified character C=a+b print(c) Concatenate (combine) two strings A=(f"my name is john, i am {age}") print(a) F-string; { } is the placeholder/modifier A = 85.8756 b = format(a, ".2f") print(b) Modifier to format the value to 2 decimal places (85.88) Price = 85. b = f"price: ${price:.2f}" print(b) F-string with placeholder for price and modifier to format value to 2 decimal places (price: $85.88) What built-in data type is used when you assign text to your variable? WGU WGU Str x = "hello, world!" x = str("hello, world!") What built-in data type is used when you assign a numeric value to your variable? Int x = 20 x = int(20) float x = 20.5 x = float(20.5) complex x = 1j x = complex(1j) What built-in data type is used when you assign a sequence to your variable? List x = ["apple", "banana", "cherry"] x = list(("apple", "banana", "cherry")) tuple x = ("apple", "banana", "cherry") x = tuple(("apple", "banana", "cherry")) range x = range(6) What is the difference between a list and a tuple? List = collection of values tuple = ordered and unchangeable What built-in data type is used when you assign a mapping to your variable? Dict x = {"name" : "john", "age" : 36} x = dict(name="john", age=36) What built-in data type is used when you assign a set to your variable? Set x = {"apple", "banana", "cherry"} x = set(("apple", "banana", "cherry")) frozenset WGU WGU x = frozenset({"apple", "banana", "cherry"}) x = frozenset(("apple", "banana", "cherry")) What built-in data type is used when you assign a boolean to your variable? Bool x = true x = bool(5) What built-in data type is used when you assign binary to your variable? Bytes x = b"hello" x = bytes(5) bytearray x = bytearray(5) memoryview x = memoryview(bytes(5)) What built-in data type is used when you assign the value none to your variable? Nonetype x = none What is syntax error? Contains invalid code that cannot be understood What is indentation error? Lines of the program are not properly indented What is a value error? Invalid value is used (e.g., int(three)) What is a name error? Program tries to use a variable that does not exist What is a type error? Operation uses incorrect types (e.g. Int(5) + string(four)) How do you check which version of python editor you have? Import sys print(on) How do you edit, save, and run a python file? Edit = can edit in a text editor save = save as run = in command prompt, type Can you run python in the command line? Type python or py you will see python version information and when you are finished, type exit( )
