Python in One Shot
This video has been made with a lot of love & I hope you guys have an amazing programming journey :)
Why to Use Python?
Python can be used for :
1
...
Development (using a backend framework called Django)
3
...
What to Install?

PyScripter (https://rb
...
PyCharm (https://www
...
com/pycharm/)
Our First Python Program
print("Hello World")
A Key Point to know about Python
- It is a case sensitive language
Variables
Basic Types in Python - numbers(integers, floating), boolean, strings
Example 1 :
name = "shradha"
age = 22
print(name)
print(age)
Example 2 :
name = "shradha"
age = 22
name = "aman"
age = 24
print(name)
print(age)
Example 3 :
first_name = "shradha"
last_name = "khapra"
age = 19
is_adult = True
print(first_name + " " + last_name)
print(age)
print(is_adult)
> Exercise Solution
first_name = "Tony"
last_name = "Stark"
age = 52
is_genius = True
Taking Input
name = input("What is your name? ")
print("Hello " + name)
print("Welcome to our cool Python class")
> Exercise Solution
superhero = input("What is your superhero name? ")
print(superhero)
Type Conversion
old_age = input("Enter your age : ")
#new_age = old_age + 2
#print(new_age)
new_age = int(old_age) + 2
print(new_age)
#Useful
# 1
...
# 3
...
converion functions
float()
bool()
str()
int()
> Code for Sum of 2 Numbers
first_number = input("Enter 1st number : ")
second_number = input("Enter 2nd number : ")
sum = float(first_number) + float(second_number)
print("the sum is : " + str(sum))
Strings
name = "Tony Stark"
print(name
...
lower())
print(name)
print(name
...
find('Y'))
print(name
...
find("stark"))
print(name
...
numbers = range(5)
print(numbers)
For iteration (see For Loop section)
While Loop
i = 1
while(i <= 5):
print(i)
i = i + 1
i = 1
while(i <= 5):
print(i * "*")
i = i + 1
i = 5
while(i >= 1):
print(i * "*")
i = i - 1
For Loop (to iterate over a list)
for i in range(5):
print(i)
i = i + 1
for i in range(5):
print(i * "*")
i = i + 1
Lists
List is a complex type in Python
...
append("physics")
marks
...
insert(0, "math")
marks
...
clear()
print(marks)
i = 0
while i < len(marks):
print(marks[i])
print(marks[i+1])
i = i + 2
Break & Continue
students = ["ram", "shyam", "kishan", "radha", "radhika"]
for student in students:
if(student == "radha"):
break
print(student)
for student in students:
if(student == "kishan"):
continue
print(student)
Tuples
They are like lists (sequence of objects) but they are immutable i
...
once they have been
defined we cannot change them
...
marks = (95, 98, 97, 97)
#marks[0] = 98
print(marks
...
index(97))
Sets
Sets are a collection of all unique elements
...
marks = {98, 97, 95, 95}
print(marks)
for score in marks:
print(score)
Dictionary
Dictionary is an unordered collection of Items
...
marks = {"math" : 99, "chemistry" : 98, "physics" : 97}
print(marks)
print(marks["chemistry"])
marks["english"] = 95
print(marks)
marks["math"] = 96
print(marks)
Functions in Python
Function is a piece of code that performs some task
...
In-built functions
# int() str() float() min() range() max()
b
...
Each module should contain some related tasks
Example : math, random, string
import math
print(dir(math))
import random
print(dir(random))
import string
print(dir(string))
from math import sqrt
print(sqrt(4))
c
