python basics Flashcards
in print what is the + used for
to join two strings
in print what is a , used for
to join a string and a int
what would the output of this line of code print(“test”,”test”)
test test , give a space
the to parts of this line are called what print(“test”)
funtion and peramitor
what is the \ used for
escaped charictor turns the next charictor into a aski eg cancels its funtion
what are the two ways of fixing the \ in file paths
replace all \ with \ or /
what are the three basic maths symbols
+ - * /
what is the turm used in programing for decimal numbers
float
what is used as the formula for the power of
**
what is the syntax for creating a var
var = 100
can you put a funtion in a variable
yes
can you write out a funtion in a varible
var = othervar / 5.3
explain while loop in a sentence
while something is the case do something
write down the start of a while loop
var = 10
while var <10:
how do you end the first line of a while loop
:
what does this code do conditon += 1 do
adds one to the variable
what does += do
adds one to a varible
what is another way to write var = var + 1
var += 1
what is the simbol for a single line comment
#
how do you comment multiple lines at once
’’’
write a quick while loop
example
var
while var <10:
var += 1
how do you stop a script running
ctl + c
what is a simpol way to make a infinite loop using while
while True:
print(“ahhh”)
write out a basic list
list = []
what will this code print
list = [1,2,3,4,5]
for thing in list:
print(thing)
1
2
3
4
5
what is a common use for if statments
iterate through list
what will this code print
for x in range (1,10):
print (x)
1
2
3
4
5
6
7
8
9
(goes up to but does not include last number)
what is the biggest diffrence between if and while
if statements only run the code once, while statements will keep running
what will the output of this code be
x = 2
y = 7
7 = 10
If x > y:
print(x,’is greater than’ y)
if x<y:
print(x,’is less than’y)
2 is less than 7
there will be spaces as a , was used
what is the diffrence between = ==
= is a assinment opperator not a comparison operator
what is the code for less than or equal too
<=
can you modify a gobal varible in a funtion
no (you would have to assign the the global var to a local var to make changes
