Python Basics

3. Variables Memory locations reserved to store values
Variables are dynamically typed
Use the equal sign (=) to assign a value to a variable
Assign a single value to several variables simultaneously
Assign multiple values to multiple variables
my_variable = “hello”
a = b = c = 22
name, age, height= "Bob", 22, ”5’11"

4. Variable Naming Variable names are case-sensitive.
A variable's name can be any legal identifier (an unlimited-length sequence of Unicode letters and digits)
Must beginning with a letter or underscore
Variables that start with an underscore (_) are treated as local and private, and cannot be imported from outside the module
When choosing a name for your variables, use full words instead of cryptic abbreviations. This will make your code easier to read and understand

5. Strings Can be concatenated: Can be formatted: Can be indexed:
"My name is " + "Jane"
"My name is " + name
Can be indexed:
name = "John”
name[2]  "h"
Can be sliced:
name = "Geraldine"
name[1:4]  "era"
Can be measured:
len(name)  9
Can be formatted:
name = "JoHn"
name.lower()  "john"
name.upper()  "JOHN"
name.title()  "John”
Can be repeated:
name = "Bob"
name*3  "BobBobBob"
Can be reversed:
name = "Geraldine"
name[::-1]
 "enidlareG

6. Lists Easy to create: Can be combined: Can be indexed: Can be sliced:
my_list = [1,2,3]
names = ["Bob", "Eva"]
Can be combined:
a, b = [1, 2], [6, 7]
a + b  [1, 2, 6, 7]
Can be indexed:
names[1]  "Eva"
Can be sliced:
my_list = [1,2,3,4,5]
my_list[1:4:2]  [2,4]
Can be sorted:
list = [4,2,6,8,3]
list.sort()[2,3,4,6,8]
Can be repeated:
list = [1,2,3]
list*2  [1,2,3,1,2,3]
Can be measured:
list = ["a","b","c"]
len(list)  3
Can be reversed:
list = [1,2,3,4]
list[::-1]  [4,3,2,1]
