Program to print the first 20 natural numbers

In this program, we will print the first 20 natural numbers using a while loop.

Steps to solve the program

Create a variable and assign its value equal to 1.
While the value of the variable is less than 21 print the variable.
Add 1 to the count variable after printing a number.
Print the output.

				
					count = 1

while count < 21:
    print(count,end=" ")
    count += 1

Output :

				
					1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

print the keys and values of a dictionary

Print the table of a number using a while loop

Print the keys and values of a dictionary

In this program, we will print the keys and values of a dictionary.

Steps to solve the program

Take a Dictionary as input.
Get the keys and values of the dictionary using items().
Use for loop to iterate over keys and values of the Dictionary.
Print the output.

				
					dict1 = {'name':'virat','sports':'cricket'}

for key,val in dict1.items():
    print(key,val)

Output :

				
					name virat
sports cricket

Steps to solve the program

Take a Dictionary as input.
Get the values of the keys of a dictionary using values().
Use for loop to iterate over keys of the Dictionary.
Print the output.

				
					dict1 = {'name':'virat','sports':'cricket'}

for value in dict1.values():
    print(value

Output :

				
					virat

    print(keys)

Output :

				
					name
sports

create an empty list and add odd numbers from 1-10

print the values of the keys of a dictionary

Create an empty list and add odd numbers to it.

In this program, we will create an empty list and add odd numbers to it from 1-10.

Steps to solve the program

Create an empty list.
Use for loop to iterate over numbers from 1-10.
During iteration check whether a number is odd or not.
Add those numbers to the empty list.
Print the output.

				
					odd = []

for i in range(1,11):
    if i%2 != 0:
        odd.append(i)
        
print(odd)

Output :

				
					[1, 3, 5, 7, 9]

create an empty list and add even numbers from 1-10

print the keys of a dictionary

Create an empty list and add even numbers in it.

In this program, we will create an empty list and add even numbers from 1-10 to it.

Steps to solve the program

Create an empty list.
Use for loop to iterate over numbers from 1 to 10.
During iteration check whether the number is even or not.
If it is an even number then add it to the empty list.

				
					even = []

for i in range(1,11):
    if i%2 == 0:
        even.append(i)
        
print(even)

Output :

				
					[2, 4, 6, 8, 10]

print each word in a string on a new line

create an empty list and add odd numbers from 1-10

Print each word on new line from the string.

In this program, we will print each word on new line from the string.

Steps to solve the program

Take a string as input.
Use for loop to iterate over each character from the string.
Print the character on the new line.

				
					str1 = "Sqatools"

for char in str1:
    print(char,end="\n")

Output :

				
					S
q
a
t
o
o
l
s

display numbers from a list

create an empty list and add even numbers from 1-10

Program to display numbers from a list

In this program, we will display numbers from a list.

Steps to solve the program

Take a list as input.
Use for loop to iterate over each element of the list.
Print the output.

				
					list1 = [1,5,8,0,4]
for val in list1:
    print(val,end=" ")

Output :

				
					1 5 8 0 4

first 20 natural numbers using for loop

print each word in a string on a new line

First 20 natural numbers using a for loop

In this program, we will print the first 20 natural numbers using a for loop.

Steps to solve the program

Use for loop to iterate over the first 20 natural numbers.
Print the numbers.

				
					
for i in range(1,21):
    print(i,end=" ")

Output :

				
					1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

Print the table of a number

display numbers from a list

Print a table of a number using for loop

In this program, we will print a table of a number using for loop.

Steps to solve the program

Take the number 5 as input to print its table.
Create a variable and assign its value equal to 0.
Use a for loop to iterate over 1-10.
Multiply the given number with the loop number and store the result in the created variable.
Print the result after each iteration.

				
					num = 5
a = 0
for i in range(1,11):
    a = i*num
    print(i,"*",num,"=",a)

Output :

				
					1 * 5 = 5
2 * 5 = 10
3 * 5 = 15
4 * 5 = 20
5 * 5 = 25
6 * 5 = 30
7 * 5 = 35
8 * 5 = 40
9 * 5 = 45
10 * 5 = 50

print the following pattern
