1. Try
Specifies exception handlers
The output to skip over to the next horizontal tab.
Some code that has been grouped together so that it can be reused by "calling" the function name. Like a mini-program within a program.
For importing a specific variable - class or a function from a module
2. Function
1. Names code like variables name strings/numbers 2. Takes arguments the way scripts take argv 3. Using 1 and 2 - allows for mini-commands
A set of specific steps for solving a category of problems
Makes lowercase
..paragraphs. Each if - elif - and else grouping is like a set of sentences. Put blank lines before and after.
3. Way to access elements
Value of two operands not equal? -similar to !=
A named entity - usually stored on a hard drive - floppy disk - or cd-rom - that contains a stream of characters.
Free-form strings
List[start:end:stride]
4. Global variable
Available everywhere
Diamond
Gives you the entire list
No argument converted - results in "%" in the result
5. %
No argument converted - results in "%" in the result
Used to determine - which statements are going to be executed
Floating point exponential format (lowercase)
Floor division. Numbers after the decimal in the quotient are removed - 9//2 = 4
6. Env
Dell
Diamond
Look at your environment
!=
7. For
\
False
Range
Iterate over items of a collection in order they appear
8. Xargs
Not
Modulus and. Takes modulus using two operands and assigns the result to left operand a%=b ~ a = a%b
True
Execute arguments
9. My_list[0:]
Converts a signed integer decimal
String format character; use for user formatting
Accumulator
Gives you the whole list - starting at the 0 position
10. Token
Basic elements of a language(letters - numbers - symbols)
Flags
Reads one line of text file
Logic
11. Str
Converts to a string
Running
Pseudocode
True
12. Argument
The "argument variable - " a very standard name in programming - that you will find used in many other languages. This variable holds the arguments you pass to your python script when you run it. You know how you type python ex13.py to run the ex13.py file? Well the ex13.py part of the command is called an "argument." What we'll do now is write a script that also accepts arguments.
A value provided to a function when the function is called. This value is assigned to the corresponding parameter in the function.
List comprehension
Compound
13. True/false: the \t escape character causes the output to skip over to the next horizontal tab.
Multiple variables that contain references to the same object.
Make directory
A file containing python definitions - statements or scripts - can be user defined or from a built-in library
True
14. Operator
A special symbol that represents a simple computation like addition - multiplication - or string concatenation.
Hardware
Bitwise xor - exclusive or - turns bits on if either but not both bits of inputs are turned on - 0b1010 ^ 0b1101 = 0b0111
Greater than or equal
15. Parameter
Variables
**
A name used inside a function to refer to the value which was passed to it as an argument.
Bitwise and - turns on bits turned on in both inputs - 0b100 & 0b101 = 0b100
16. %e
Pop directory
A named sequence of statements that performs some useful operation. Functions may or may not take parameters and may or may not produce a result
Floating point exponential format (lowercase)
To repeat an operation on all members of a set from the start to the end.
17. Semantic
The meaning of a program
Letters = ['a' - 'b' - 'c' - 'd' - 'e'] - slice = letters[1:3] - print slice - print letters
76.159
Executes python code dynamically
18. Function import
A whole number
Import a function from a module - (from module import function)
255
A formatter text that is used to give the user the ability to type in a question
19. Popd
My_list[3:]
Start at 1; first - second - third
Pop directory
Reads one line of text file
20. The _____ built-in function is used to read a number that has been typed on the keyboard.
True or false
The meaning of a program
Input()
Close()
21. \n
1) header def function and add parameters 2) add additional """comment here""" that explains the function 3)body describes procedures the function carries out - is indented
Ascii linefeed (lf) - goes to next line -newline escape
Used to interrupt the current cycle - without jumping out of the whole cycle. New cycle will begin.
Signed octal value
22. Useful for information using strings and values i.e. phonebook - email databases (passwords - and usernames)
To test if a condition is true (e.g. if age >17)
D = {'key1' : 1 - 'key2' : 2 - 'key3' : 3}
- script = name of python script - first - second - third = 3 variables arguments assigned to
Signed octal value
23. Sequence
A data type that is made up of elements organized linearly - with each element accessed by an integer index.
To repeat a commands a set number of times.
The number that each character in a string is assigned
Read a manual page
24. Variables can be reassigned?
True
Danger! Become super use root! Danger!
A python data type which stores floating-point numbers. Floating-point numbers are stored internally in two parts: a base and an exponent. When printed in the standard format - they look like decimal numbers
Bitwise not - flips all bits in a number - for integers - effectively adds 1 and makes negative
25. What type of loop structure repeats the code based on the value of the boolean expression
Condition-controlled loop
While condition : statement
For
A named entity - usually stored on a hard drive - floppy disk - or cd-rom - that contains a stream of characters.
