ASK NO QUESTION, FOR EACH STEP DO IT THE WAY YOU SEE IT !!

DONT ASK WHY, IF YOU DO IT THE WAY YOU SEE IT YOU WILL ANSWER YOUR OWN QUESION

THE ONLY WAY TO LEARN IS BY DOING :)

to write a function

remeber the return statement

def my_function(a,b,c,d,e,f):
    print(a + f)
    print(b+c)
    print(d+e)
    return 'what you need to finsih'
# function ends here

to call a function

if the function have 6 parameters you give it 6 arguments if the function have 7 parameters you give it 7 arguments if the function have 12 parameters you give it 12 arguments

my_list = [1,2,3,4,5,6]
function_answer = my_function( *my_list)
print(function_answer)

to make a variable

no quotes ,no #, no spaces write with only lowercase letters and underscore if you see something like this @^$^@ only use it dont write like it

variable = 1 
abc 
my_friend

_sadgsakdgnmsadgk__  
$@%%@%^ = 12

strings

string - they are for humans to read these are regular strings always wrapped in " "

THEY ARE NOT WORDS, WE CALL THEM 'STUFF' a string is full of stuff one "stuff " one string two "stuff " "stuff " two strings several "stuff " several strings

"mystring" 
"cn2r8qo89c 82qhx832rq8yh8uq2   2r33    2r2 w" # string


"adgoawdg" "sadgsdgFfdsFS"
"" "" "" "" " "

head = "1"
tail = "2"

answer = "my boss name is vaquero, my boss is getting a raise"
"$@#%&#^&%$*%(&*^$&@^*&#^%&$$# dasonskmnfkag"
"#@%7%&##$@^dasgASDGasg"
"lol, wyd, txt me ltr, "

\n is the newline char in python

that \n would put what ever is after the string on a new line FOR REGULAR STRINGS ONLY

# what python
"Step on my feet\n watch your twos"

"Step on my feet"
"watch your twos"

byte strings

they are used for encryption encoding, decoding, hashing, ssh lock key lock key public key private key, key to your house (lmao) all that good stuff

THEY ARE STRING WITH b AT THE FRONT- THATS HOW YOU WRITE THEM NO QUESTIONS WRITE IT LIKE THAT THEY ARE NOT BYTES THEY ARE BYTE STRINGS all they are used for is to convert one item to another

my_byte_string = b'this is my password'

your_byte_string = b'this is your password'


import binascii

binascii.b2a_base64(your_byte_string)
b'dGhpcyBpcyB5b3VyIHBhc3N3b3Jk\n'


binascii.a2b_base64(b'dGhpcyBpcyB5b3VyIHBhc3N3b3Jk\n')
b'this is your password'


binascii.b2a_hex(your_byte_string)
b'7468697320697320796f75722070617373776f7264'

binascii.a2b_hex(b'7468697320697320796f75722070617373776f7264')
b'this is your password'

to convert

your_byte_string = b'this is your password'
str(your_byte_string)
'this is your password'

your_string = 'this is your password'
your_string.encode()
b'this is your password'

to run a python file

python3 name_of_your_file.py

to add user arguments

in terminal to add more arguments seperate by space

python38 learn.py user_has_to_say



python38 store.py soap shampoo toliet_paper tissue

python38 store.py mimi pizza bathtub sink

to see user arguments in python

import sys
print(sys.argv)

create a list

my_list = ['strings',2,['another','list'],('my','tuple'),3{and:'more',for:'more'}]

a_list =[1,2,3,4,5]

a_list =['string','strings','stuff']

list index

with a bracket and a num at the end like this my_list[1] num has to be less them anout of items in list

a_list =['string','strings','stuff']

a_list[2]  # right
a_list[16] # wrong

index by slice

this gives a part of the list give another list

s_l = ["stuff",1,"a",34,["anohther"],21]

print(s_l[0:1])
print(s_l[0:2])
print(s_l[0:3])
print(s_l[0:4])
print(s_l[0:5])
print(s_l[0:6])

print(s_l[2:3])
print(s_l[2:4])
print(s_l[2:5])
# so you can start and end anywhere in the list

print(s_l[5:len(s_l)])
print(s_l[4:len(s_l)])
print(s_l[4:len(s_l)])
print(s_l[3:len(s_l)])
print(s_l[2:len(s_l)])
print(s_l[1:len(s_l)])

to loop in python

my_list = ['loop','thorough','this','list']
for index in  my_list:
    print(index)

this is how python counts

my_list = ['loop','thorough','this','list']
counter = 0 
for toys in my_list:
    # print(toys)
    counter += 1
#end of for loop
print (counter)

while loop

when a loop has a reason to stop counting you need your counter variable the reason to stop here is "hello strin

counter = 0 

my_list = [22,22,22,22,22,22,22,"stopping at next word","hello",22,22,22]
while my_list[counter] != "hello":
    print(my_list[counter])
    counter = counter + 1
#end of while loop

to read to a file in python

make sure target file is in the same folder as the host program

with open('samplefile.txt','r') as f:
    text = f.read()
    text_list = text.split("\n")

    #or 
    for line in f:
        print(line, end='')    
#end of functiion

to write to a file in python

make sure target file is in the same folder as the host program

with open('samplefile.txt','w') as f:
    f.write('This is a test\n')
#end of functiion

to make a dictionary

key - the left side only string,number, value, - the right side anything go there index - dictonary[key], gives you the value

every key value entry seprate with comma every entry looks like this

'key':'value'

car_dictnary = {
    'key':1          ,
    'door':4             ,
    'make':'toyota'         ,
    'model':'SUV'             ,
    'YEAR':['03','04','05']    
}

to get key from a value

print(car_dictnary['key']   )
print(car_dictnary['door'])
print(car_dictnary['make'])
print(car_dictnary['model'])
print(car_dictnary['year'])

to loop through dictonary

for keys,val in car_dictnary.items():
    print(keys,val)
#end of loop

to create a client socket

import socket 
HOST = 'listen.runcode.ninja' #name of server here
PORT = 80 #is a port
ADDR = (HOST,PORT)
client_msg  = "My message for the server"  
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:

    #connect to  a socket
    s.connect(ADDR)    
    ################################

    client_msg = client_msg + "\n"
    client_msg = client_msg.encode()
    s.send(client_msg)
    server_msg = s.recv(1024)
    server_msg =server_msg.decode()
    print(server_msg)
    # print(msg)

request and response

import requests 

url = 'http://blackjack.runcode.ninja'

modify the url to get different pages or different data from the server 
url = 'http://blackjack.runcode.ninja/bj.php'
url = 'http://blackjack.runcode.ninja/aboutPage'
url = 'http://blackjack.runcode.ninja/adminPage'


website = requests.get(url)
print(website)

requests and response Session

when you want to steal someones session when they login to their bank acct

import requests 

url = "http://tdbank.com"
sess = requests.Session()
stolen_rich_person_session = sess.get(url)
money = '$0 USD'


while money != '$10000000 USD':

    transfer_money = sess.post(url,data = transfer)
