1: Python Program To Add 2 Numbers
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))
sum = num1 + num2
print("The sum of", num1, "and", num2, "is", sum)
print("Program By Nikhil")
2: Python Program To swap Two Values Without Using Third value and Display New
Value
a = float(input("Enter first number: "))
b = float(input("Enter second number: "))
a, b = b, a
print("After swapping:")
print("First number:", a)
print("Second number:", b)
print("Program By Nikhil")
3: Python Program To make a calculator
while True:
print("Select operation:")
print("1. Add")
print("2. Subtract")
print("3. Multiply")
print("4. Divide")
choice = input("Enter choice (1/2/3/4): ")
if choice in ['1', '2', '3', '4']:

print("Cannot divide by zero!")
else:
result = num1 / num2

else:
print("Invalid input. Please enter a valid choice.")
again = input("Do you want to perform another calculation? (yes/no): ")
if again.lower() != 'yes':
print("Exiting the calculator. Program Made by Nikhil")
break
4: Python Program To Check Whether A Character Is Small Or Capital
char = input("Enter a character: ")
if len(char) == 1:
if char.islower():
print("Small letter")
elif char.isupper():
print("Capital letter")
else:
print("Not a letter")
else:
print("Please enter a single character.")
print("Program By Nikhil")
Python program to change one datatype to another:
num_str = "123"
num_int = 456
num_float = 78.90
num_list = [1, 2, 3]
str_to_int = int(num_str)
int_to_float = float(num_int)
float_to_str = str(num_float)
list_to_tuple = tuple(num_list)
tuple_to_list = list(list_to_tuple)
print("String to Integer:", str_to_int)
print("Integer to Float:", int_to_float)
print("Float to String:", float_to_str)
print("List to Tuple:", list_to_tuple)
print("Tuple to List:", tuple_to_list)
Python Program To :
(i):Traverse A List:
my_list = [10, 20, 30, 40, 50]
print("Traversing using a for loop:")
for item in my_list:
print(item)
print(“Code By Nikhil”)
(ii):A 2d List:
my_list = [[10, 20, 30, 40, 50]]
for i in my_list:
for item in i:
print(item)
print("code by Nikhil")
(iii)Python Program To Receive A List From User & Traverse It:
my_list = []
i=0
while True:
a=eval(input("Enter List Element :"))
my_list.append(a)
i=+1
again=input("AGAIN? y/n:")
if again=="n":
break
for item in my_list:
print(item)
print("Code By Nikhil")
7: Python Program To receive string from user and traverse it:
user_input = input("Please enter a string: ")
for i in user_input:
print(i)
print('program by nikhil')
Q_8 write a program to display table of any given no.?
CODE :-
number=int(input("enter any no,"))
for i in range(1,11):
print(number,"*",i,"=",number*i)
print(“program by Nikhil”)
Q-9 Write a program to following string function
(capitalize,alnum,split,replace,partition)
st="this is string function'
print(st.split("i"),"THIS IS SPLIT FUNCTION")
print(st.replace("is","was"),"THIS IS REPLACE FUNCTION")
print(st.partition("i"),"THIS IS PARTITION FUNCTION")
print(st.capitalize(),"THIS IS CAPITALIZE FUNCTION”)
print(st.isalnum())
print(“program by Nikhil”)
Q10 Create a dictionary of month where month name is key and number of days
is value now ask a user for a month name and display no. of days in that month
?
CODE:
months_days = {'January': 31,'February': 28, 'March': 31,'April': 30,'May': 31,'June': 30,'July': 31,'August':
31,'September': 30,'October':31,'November': 30,'December': 31}
month = input("Enter a month name: ")
print(month,"no. of days is",months_days[month])
print(“program by Nikhil”)
