HOW TO USE THE DIFFERENT FUNCTIONS WITHIN THE RANDOM LIBRARY
correct answers use:
from random import ___
use from random import randint when wanting to generate random integers
use
from random import randrange, lets you import a range of numbers and gives you a random
number within the numbers given. Ex: (1,6) -- gives a random number from 1 to 5
use
from random import rand
When declaring variables in Python, a data type must be specified
True of False correct answers false
Python makes the distinction between integers and floating variables.
True of False correct answers True
When setting a boolean variable, the value must start with a capital letter
True of False correct answers True, meaning it must begin with True or False
what are concatenation symbols correct answers commas if different data type and plus signs
if they are the same data type
improper syntax of way the varibles are written when declared correct answers spaces and
dashes should not be used when declaring variables
evaluate this statement:
a =5
b=3
b=a correct answers since b = a then a == b and b = 5 not 3 anymore, so a is b
what keywork in python checks to seee if a number or text is available correct answers the
keyword "in" and then the name of the variable
code to print our letter grades of students correct answers def grades():
if score >=90: grade = 'A'
if score >=80: grade = 'B'
if score >=70: grade = 'C'
else:
grade = 'F'
WHAT keyword is used as a placeholder for a conditional result? correct answers pass
, the while keyword starts a ... correct answers loop
what does the continue keyword do correct answers skips a turn in the loop
difference between \ , \n ,\\, and \t correct answers the symbol \ tells python to continue the
statement on the next line
\n tell python to print a new line
\t tells python to insert a tab
\\ tells python to use the \ character
how to open a file and read it // without being able to write in it correct answers
variableName = open ('fileName', "r")
newVariableName = variableName.read()
print (newVariableName)
how to free up the memory that a file has been using after opening a file correct answers
using the example below:
variableName = open ('fileName', "r")
newVariableName = variableName.read()
print (newVariableName)
to close:
variableName.close()
How to get this file to only read the first line:
workFile = open('work.txt', 'r')
workFileFirstLine = __________?
print (workFileFirstLine) correct answers workFile.readline()
.readline is a built in function that reads the first line
when using python in a command line environment, what command will list available python
commands and show information on these commands when an individual command is
entered? correct answers help ( )
difference between user, logic, runtime and syntax error correct answers user - idk
logic - program doesnt crash, but produces an incorrect result , cause by mistake in the
programs logic
runtime- can include division by 0 , in summary with a runtime error you get your code to
start but as the program is running it stops because of an error
syntax- python doesnt understand ur code and cant run it
methods to use when trying to write code that handles errors gracefully correct answers USE:
