day - 9 at payilagam python looping

Programming rules:
i) Known to unknown
ii) Don't think about the entire output
iii) Think only about the very next step
iv) Introduce variable if neccessary
v) Observe program closely

PYCACHE:

The pycache folder is a directory created by Python that stores compiled bytecode files (.pyc) of your Python scripts. This helps speed up the execution of your programs by allowing Python to use the pre-compiled bytecode instead of reinterpreting the source code each time.

program for 5 consecutive numbers:

count = 1
if count<=5:
    print(1, end=' ')
    count=count+1 #count = 2
if count<=5:
    print(1, end=' ')
    count=count+1 # count = 3

if count<=5:
    print(1, end=' ')
    count=count+1 # count = 4

if count<=5:
    print(1, end=' ')
    count=count+1 # count = 5

if count<=5:
    print(1, end=' ')
    count=count+1 # count = 6

output:

1 1 1 1 1

count = 1
while count <= 5:
    print(1, end=' ')
    count += 1

output:
1 1 1 1 1

The difference between two programs are same but when we can easily print upto five but when it comes to 100. it takes more time so, by easily introducing the variable into loop. we can easily write the program.
mainly it reduces time, for this while operator is used.

print("Hello", "World", sep=" , ")

Hello , World

print("ragu",'raju','ravi',sep='-')

ragu-raju-ravi

print("Hello", end="$")
print("World")

Hello!World

The difference between sep and end is sep adds the symbol in between the string and the end adds the symbol which is given by the user at the last.

def add(no1,no2):
    print(no1+no2)
add(10,20)

arguments which are passed defines the function is called positional argument.
It is a positional argument.

variable - length arguments.
Allow passing a variable number of arguments.

n Python, *args is used to pass a variable number of arguments to a function. It is used to pass a variable-length, non-keyworded argument list. These arguments are collected into a tuple within the function and allow us to work with them.

from datetime import date
current_date=(date.today())

print("Current Date:",current_date)

Current Date: 2024-11-25

import only date using python
