python day 2

##------------------------------------------ Task 1 --------------------------------##

## Simple Calculator

x = 10
y = 20
total = x + y
print(total, type(total))

x = 10
y = 20
total = x - y
print(total, type(total))

x = 10
y = 20
total = y / x
print(total, type(total))

x = 10
y = 20
total = y % x
print(total)

## Type Conversion

x = 10
y = 5

print( float(x) / float(y) )

x = 100
y = 5
x_str = str(x)
y_str = str(y)
total = x_str + y_str
print(total, type(total))

x = "10"
y = "5"
x_int = int(x)
y_int = int(y)
total = x_int + y_int
print(total,type(total))

x = 99.8
x_int = int(x)
print(x_int, type(x_int))

x = 5
y = "5.2"
z = 3

x_float = float(x)
y_float = float(y)
z_float = float(z)

print(x_float, type(x_float))
print(y_float, type(y_float))
print(z_float, type(z_float))

## Input function

name = input("Enter your name : ")

print("Good Morning", name)

## Calculator with input fn()

first = input("Enter your first number : ")
second = input("Enter your second number : ")
third = input("What you want to do add/substract/divide : ")

if third == "+":
  add = int(first) + int(second)
  print(add)
if third == "-":
  sub = int(first) - int(second)
  print(sub)
if third == "/":
  div = int(first) / int(second)
  print(div)

## Comparison operators

x = 10
y = 5

r = x > y
print("x > y", r)

r = x < y
print("x < y", r)

r = x >= 20
print("x >=20 ", r)

r = x <= 10
print( "x <= 10", r)

r = x == y
print("x == y", r)

r = x == 10
print("x == 10", r)

r = x != 10
print("x != 10", r)

r = y != 10
print("y != 10", r)

## String comparison

str1 = "abc123"
str2 = "abc123"
str3 = "abc"

result = str1 == str2
print(result)

result = str1 != str2
print(result)

result = str3 == str2
print(result)

## Len function

name1 = "prince"
name2 = "chris"
name3 = "Vysakh UT"

result = len(name1)
print(result, type(result))

result = len(name2)
print(result, type(result))

result= len(name3)
print(result, type(result))

port = 8080
result = len(str(port))
print(result, type(result))


## Membership Operation

fruit = "Pineapple"
result = "apple" in fruit
print(result)

result = "in" in fruit
print(result)

result = "p" in fruit
print(result)

result = "P" not in fruit
print(result)

## Subscript Operation

name = "Richard"
r = name[0]
print(r)

r = name[3]
print(r)

## If else condition

num = input("Enter a number : ")
x_int = int(num)

if x_int >= 10:
  print("The number is greater than 10")
else:
  print("Sorry the number is less than 10")


##------------------------------------------ Task 2 --------------------------------##

## 1] Print the length of the string

word = input("Enter the word so as to count the n.o of characters : ")
print( "The length is : ", len(word))

Ans] Enter the word so as to count the n.o of characters : Kerala
The length is :  6

## 2] Check the substring is present

word = input("Enter the word : ")
sub = input("Which word to check : ")
if sub in word:
  print("Yes there is", sub , "in the word", word)
else:
  print("Sorry no match found")

Ans ] Enter the word : Pineapple
Which word to check : apple
Yes there is apple in the word Pineapple

## 3] Check the number is odd or even

num = input("Enter the number to check whether it's odd or even : ")
x_num = int(num)
if x_num % 2 == 0:
  print( "The n.o", x_num , "is even")
else:
  print( "The n.o", x_num , "is odd")

Ans] Enter the number to check whether it's odd or even : 5
The n.o 5 is odd

## 4] check the word that starts with "a" or "A"

word = input("Enter the word : ")
check = word[0]
if check == "a" or check == "A":
  print("okay")
else:
  print("No")

Ans] Enter the word : Apple
okay
