Day -04 of learning python(02-22-2025)

The things i learned form todays python course:

Lambda function:

It is one most important important function used in python programming.

on going depth i found that it is anonymous function used in code .It is mainly used in on line function for example :

numbers = [1, 2, 3, 4, 5]
squared = list(map(lambda x: x ** 2, numbers))
print(squared)  # Output: [1, 4, 9, 16, 25]

In above example list is given and in that list using lambda function we found the square of the whole list i.e in sqaured variable.

The basic idea used in above example or anyother example or program is used like :

lambda(parameter:expression)

or lambda(argumensts:expression)

Map:

It helps to iterate every single value present in the list.

taking an example:

numbers = [1, 2, 3, 4, 5]
squared = list(map(lambda x: x ** 2, numbers))
print(squared)  # Output: [1, 4, 9, 16, 25]

In above example map is used for sqauring every single of the value in the list .

Also some basic stuffs like how swap values in the list ,more about IDctionary and all .

This much only for today.

Day-03 of Kapil’s learning python programming

The things i learned from python are:

1.More i.e. depth in list:

In list i learned about many thing about the proper use of list:

like we can use this in many function i.e. inside the function:

like list(a.range(5,3))

I get to know that list has many importance in programming language.

2.Set :

The new thing i learned in today’s course is about set .

it also have many use in function basically it is basically use for the mathematical problems

for example:::

set1={1,2,3,4,5}
set2={2,9,8,5,4,3}
print(set1.union(set2))
print(set1.intersection(set2))

In above code we are basically finding union and intersection using set function.

I got this idea from a channel called apnacollege.

Overall we can understand that set is widely used while mathematical problem.

3.Dictionary :

In Dictionary (one the function or “method” i learned about storing a data in a ordered manner.

I had little problem between list and dict. then i got to know that list store data in a single line ,where as dict. stored data in multiple line… :)

for example :

#Dictioanries are used to store data values in key:value pairs 
#They are unordered,mutable(changeable)
info ={
    "key":"value",
    "name":"Apnacollege",
    "learning":"python",
    "subjects" : ["java","c++"],
    "AGE":35,
    "is_adult":True,
    "marks":95.69,
}
print(info)

we can check yourself what the data could be…

i also learned some very basic stuff which i have already shared in my previous day’s Blog

so please go there and check it out

and yes “ I AM BATMAN”

Thank you this much for today

Day -02 of learning python programming language..

The thing i learned from python today are as follow:

Tuples:

simply tuples is immutable which means that we can change the data again in list.

taking as an example:

list=(1,2,3,4)
print(list)

In tuples list are stored in curly bracket({}).

It is quite faster than that of list.

2.list:

simply we can say that list is mutable which means that we can edit the list as our wish anytime.

Take any list like :

list student={kapil , Prashant , rajan}

we can use function which are inbuilt ;
list. Append()=for adding element in list .

list .insert()=for adding an element wherever you like to .

list. Replace()=For replacing the data

and so in

it is quite slower comparing to tuples .

we can do list slicing i.e. can print the data from where we want by keeping some range.

numbers = range(5,10,2)
for number in range(5):
print(number)

In list data are stored in the square bracket ([ ]).

Data can be edited easily .

function :

The most important part of this idea is def( define function )

CODE:

def sigma(to="world"):
print("noob,", to) # Added a space after the comma for better formatting

sigma()
name = input("What's your name? ")
sigma(name)

If you have any query related to above query than feel to ask.

CODE:

scope.....

return .....

def main():
name = input("What's your name?")
hello(name)

def hello(to="world"):
print("hello", name)

main()

That’s all for today’s python course..

Day-01 of learning python

KAPIL SHAH — Wed, 19 Feb 2025 17:27:25 +0000

I learned some basic stuffs in python programming language

LIKE:::

1.airthmetic operators:

python
x=10
x=x+3
x +=3

2.comparison process in this language:

# x=3!=2
# print(x)
# >
# >=
# <
# <=
# ==
# !=

3.for loops:

numbers=[1,2,3,4,5,6]
# print(numbers)
for item in numbers:
    print(item)

i=0
while i<len(numbers):
  print(numbers[i])
  i=i+1

4.if statement :



temp = 25


if temp > 30:
    print("It's hot bebe")
elif temp > 20:
    print("not hot")

5.lists :

We can say that list is mutability which means that we can insert the element even after the creation at first.

taking example :

There are three basic types from which we can define properly that what exactly is list and its use:::

1.insert() : we can insert any data or element in the square bracket :

# Insert

fruits.insert(1, "banana")
print(fruits)  # Output: ['apple', 'banana', 'blueberry', 'cherry', 'date']

2.Append (): this helps to insert the data at the last of the list :

# Append
fruits.append("date")
print(fruits)  # Output: ['apple', 'blueberry', 'cherry', 'date']

3.Extend(): This helps to Extend the list

taking an example::

# Extend
more_fruits = ["elderberry", "fig"]
fruits.extend(more_fruits)
print(fruits)  # Output: ['apple', 'banana', 'blueberry', 'cherry', 'date', 'elderberry', 'fig']

for mutual extend example we see that:

list1 = [1, 2, 3]
list2 = [4, 5, 6]

list1.extend(list2)
print(list1)  # Output: [1, 2, 3, 4, 5, 6]

from above example we see that list1 just got extended because of addition of list2

6.Logical operator:

# price = 25
# print( not price > 10 )
# and(both)
# or(atleast1)

7.Receiving inputs ::

name = input("What is your name?")
print("Hello "  + name)

8.strings

sentence=("kops the great")
print(sentence.replace('the','is'))

print(sentence.find('the'))
print(sentence.upper())
print(sentence.lower())
print(sentence.casefold)
print(sentence.endswith('true bitch'))
print('python' in sentence)
print('the' in sentence)

Kind of range and function::

numbers=[1,2,3,4,5,6]
# numbers.clear()
print(10 in numbers)

10.Type conversion(Most important)

# birth_year= input("Enter your data of birth:")

# age = 2020 - int(birth_year)
# print(age)    

num1=input("FIRST NUM:")
num2=input("SECOND NUM:")
sum= float(num1)+float(num2)
input("Sum is : " + str(sum))

It helps a lot in large program so it is most necessary to understand about These concept .

11.Variable(Kind of a container where different types of data are stored) ::


patient_name="jhon smith"
age ="20"
patient_type="New patient"
print("patient name is :",patient_name)
print( "age is :",age)
print("patient is:", patient_type)

Here patient _name ,age, patient_type is a variables::

Question times::

1.Suppose you were given a number either in kg or pound. If it is kg the convert it to pound and vice versa.

And print the statement in proper format

Incase you are having a problem on this the check it out pls>>

weig = float(input("Weigth:"))
conversion= input("kg or lbs")

if conversion == "kg":
     result=weig/0.45
     print("The weight in lbs is:" + str(result))
else :
    result = weig*0.45
    print("The weight in kg is :" + str(result))

NOTE :: OUTPUT ARE NOT GIVEN ABOVE SO YOU HAVE LOOK FOR THIS YOURSELF IN ANY COMPILER .

THANK YOU AND THAT”S FOR THE DAY 1.
