• Take a list say ‘prime_numbers’ and initialize it with 2, 3 values.
• Take a variable and initialize it with 3 say ‘x’.
• Check if the given number is between greater than 0 and less than 3 using the if conditional statement.
• If the statement is true, then print the value of the list “prime_numbers[n-1] “.
• Check if the given number is greater than 2 using the elif conditional statement.
• Iterate the loop infinite times using the while loop i.e while(True).
• Inside the loop increment the value of the above given ‘x’ variable by ‘1’.
• Take a variable to say ‘y’ and initialize with ‘True’.
• Loop from 2 to int((x/2)+1) using the for loop and int function().
• Check if the value of variable ‘x’ modulus iterator value is equal to zero or not using the if conditional statement.
• If the statement is true, assign “False” to the variable y, break the statement and come out of the loop.
• Check if variable y is equal to True using the if conditional statement.
• If the statement is true, then append the value of variable ‘x’ to the above list ‘prime_numbers’.
• Check if the length of the above list ‘prime_numbers’ is equal to the given number.
• If the statement is true, then give a break statement and come out of the while loop.
• Print the value of the list “prime_numbers[n-1]” to get the nth prime number.
• Else print “Invalid number. Please enter another number “.
• The Exit of the Program.

Strontio numbers:

Strontio numbers are four-digit numbers that, when multiplied by two, produce the same digit in the hundreds and tens places. Keep in mind that the input number must be four digits.

example :

Let N= 1386

A number multiplied by 2= 1386*2=2772

2772%1000 =772

772/10 = 77

77/10 = 7

77%7= 7

if (77%7 == 77/10 ), then it is strontio number.

Therefore 1386 is strontio number.

some of the examples of strontio numbers are :

1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, 1001, 2002, 3003, and other numbers.

Examples:

Example1:

Input:

Given number = 1001

Output:

The given number 1001 is strontio number

Example2:

Input:

Given number = 1234

Output:

The given number 1234 is not a strontio number

# another variable say 'b'.
b = a//10
# Again divide the variable 'b' by 10 to remove the last digit (quotient)and
# store it in another variable say  'c'.
c = b//10
# Calculate the value of b%10 to get the remainder and store it in another variable

Evil Number :

The Evil number is another unique positive whole number with an even number of 1s in its binary representation.

example:

1) let n= 12

binary representation = 1100

# It has an even number of 1’s.  Therefore 12 is an evil number.

2) n= 4

binary representation = 100

It has an odd number of 1’s.  Therefore 4 is not an evil number.

Examples:

Example1:

Input:

Given Number = 6

Output:

The given number 6 is an Evil Number

Example2:

Input:

Given Number = 22

Output:

In the previous article, we have discussed Python Program to Divide a String in ‘N’ Equal Parts.
When each character in a string is converted to an ASCII value, a list of corresponding ASCII values for each character is returned. Converting each character in “dce” to an ASCII value, for example, yields [100, 99, 101].

Given a string and the task is to convert each character in a given String to an ASCII Value.

ASCII Characters:

The standard range of ASCII, which stands for American Standard Code for Information Interchange, is “Zero” to “One Hundred and Twenty Seven”.

ASCII codes are used to represent text in computers and other electronic devices. The character-encoding schemes used in most modern telecommunications equipment are based on ASCII.

As a result, everything else falls into the category of “non-ASCII” character.

ord() function: To determine the specific ASCII value of that character.

Examples:

Example1:

Input:

Given String = " btechgeeks"

Output:

The given string after convering each character to an ASCII value : [98, 116, 101, 99, 104, 103, 101, 101, 107, 115]

Example2:

Input:

Given String = "hello this is btechgeeks"

Output:

The given string after convering each character to an ASCII value : [104, 101, 108, 108, 111, 32, 116, 104, 105, 115, 32, 105, 115, 32, 98, 116, 101, 99, 104, 103, 101, 101, 107, 115]

• The Exit of the Program.

Below is the implementation:

# Give the string as static input and store it in a variable.
gvn_str = "hello this is btechgeeks"
# Take an empty list say "ASCII_vals" and store it in another variable.
ASCII_vals = []
# Loop the above-given string using the for loop.
for itr in gvn_str:

  # and store it in another variable.
    a = ord(itr)
# Append the above obtained ASCII value of the iterator to the above-initialized
# list "ASCII_vals" using the append() method.
    ASCII_vals.append(a)
  # Print the given string after converting each character to an ASCII value.
print("The given string after convering each character to an ASCII value :", ASCII_vals)
