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("1\n2\n3") print using newline characters print( ) print a blank line python file.py run a script file random function 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" 1 / 2
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(a.upper( )) display a in console in upper case print(a.lower( )) display a in console as lower case print(a.strip( )) remove whitespace at beginning and end print(a.replace("H", "J")) replace a string with another string print(a.split("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 = 85.87562649 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?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)
