Hello this thread is open to post series of code in python that can less the amount of code written for simplicity in coding and creating your project with less code as possible.

I wish this thread will be clean as possible hope the can grant the creator of each post power to screen out spammers

Am starting with list

You can populate your list with a single line of code

#old coding practice to populate list object
Elements = []
for element in range (10):
    Elements.append(element)
print(Elements)

#new coding practice to populate list object
Elements = [ element for element in range(10) ]

#how to print negative numbers
Elements = [ element for element in range (0,-10,-1)]

#old way of finding square of a number
def old_square (num):
    return num*num

#fastest way 
square = lambda num : num*num

print(old_square (5)) #output is 25
Print(square (5)) #output is 25

There are factually no cheats in Python nor any other language.


What u tried to demonstrate in the first example is known as list comprehension.



Its good practice in programming, as is in other professions, to give the right name to the right concept




Don't misslead the public


Thanks.

I personally called them cheat because they are short cut in getting things done....dont be offended if the naming sounds bad to you

Python sweet sha. Plenty syntactic sugar. If you're unlucky and get hooked, you may find it difficult to detach. Rough guess sha cuz I've only used it to setup an RPC server between my dominant language.

It strikes me as very feminine — object and method name concision, package names, ease of use etc.

Nice thread op

#old way of file operation
f=open('test.txt','rb')
f.write(b'hello world')
f.close()

#fast way
with open('test.txt','rb') as f:
    f.write(b'hello world')

Lol feminine language? this one loud and sounds true!

too easy!

#in some cases you may want to assign value to some variable that are nearing #in the same category or having mutual relationship

#old way is

a="hello"
b="world"
c="!!!"

#good programming is
a,b,c='hello', 'world', '!!!'

a,b,c= 'hey','hello','world'

#old string formating
print(a,b,c)

#new string formatting
print(f'{a} {b} {c}')

#bad style
X = X + 1  

#good style
X += 1    #can be use for other arithmetic operations 

# To accept multiple variable into a function
def num(*arg):
    print(*arg)

num(1,2,3,4)  # output = 1 2 3 4
num(1) #output=1
num('hello','world')   #output=hello world

# To accept multiple keyword variable into a function
def num(**a):
    for i,k in a.items():
        print(k)

 
num(a="heloo",b="5" ) #output hello,5
 

#how to output dict variable

Nums = {"one" : 1,"two" =2, "three" : 3 }
for key,value in nums.items():
    print(f'{key} - {value}')

#output
# one - 1
#two - 2
#three - 3

#how to arrange a list in ascending order
sorted([3,6,1,2]) #output [1,2,3,6]

#in decending order
sorted([3,6,1,2],reversed = True) # [6,3,2,1]

# how to search for index of multiple chars in a string
s='sleep'

#first index of e 
# hint: the syntax of index method is index( string, start, stop) 
# string - the string to search
# start - where to Begin search,by default search Begin at 0 i.e the beginning of the string
# stop - where search to stop ,by default search stop at the end of the string

f_index = s.index('e') #output = 2

S_index =s.index('e', 3) #output = 3

#using iteration to find more than 2 chars in a string

s=' sleeping eeee '
Start_position=0
for i in range(s.count('e')):
    Start_position = s.index('e' , Start_position)
    print(f' e found at position: {Start_position}')
    Start_position+=1

pls which tool can i use too execute a program like python

I don't really your question.... Do you mean IDE?

the Python interpreter for your OS from Python. org

Nice thread OP

#Run math python script and expression with eval()
#Take for instance input = 2+4*5-6 
#instead of writing long algorithm you can solve easily with eval()

Math_expression = input(' type your math expression :')
try: 
    Ans = eval(math_expression)
    print(f'output : {Ans}')
except:
    print('invalid basic math operations')

Input : 2+4*5-6
Output : 24

Be careful when using this function because your system can be access through this....the eval() just help to run python script which means any python script can be run through eval()

#how to map two lists of equal length together
y=[7,8,3]
x=[1,2,3]
for i in zip(y,x):
    print(i)

Output
(7,1)
(8,2)
(3,3)

Thanks ���

num=list(range(5))
print(num)

#output [1,2,3,4]

#set is used for removing duplicate from ordered list

Num=set(1,1,3,2,6,2,4,5)

#output = (1,2,3,4,5,6)

#to get help info about any particular module or inbuilt function you can use help() let see how to use below

print( help(int))

output:
