Write a program that first reads in the name of an input file, followed by two strings representing the lower and upper bounds o

f a search range. The file should be read using the file.readlines() method. The input file contains a list of alphabetical, ten-letter strings, each on a separate line. Your program should output all strings from the list that are within that range (inclusive of the bounds). Ex: If the input is: input1.txt ammoniated millennium and the contents of input1.txt are: aspiration classified federation graduation millennium philosophy quadratics transcript wilderness zoologists the output is: aspiration classified federation graduation millennium

Answer:

Python code explained below

Explanation:

f = open(input())

#loading the file, which will serve as the input

s1 = input()  

s2 = input()

lines = f.readlines()

for line in lines:

   line = line.strip(

# strip() removes characters from both left and right

   if s1 <= line <= s2:  #setting the range

       print(line)

f.close()

#closing the file

If my_string = "This is MY string!", why does print (my_string[0:7:5]) return "Ti" and not
notka56 [123]

In Python, a string is an array of characters, we can access these characters using index operator []. For example, we have a_string = "Hello World" a_string[0] prints the first character in string ('H').

We can also use index operator to make substrings, for example a_string[0:3] will make a substring with first, second, third and fourth character equal to "Hell".

Now to business

my_string = "This is MY string!"

print(my_string[0:7]) # Prints "This is "

print(my_string[0:7:5]) # Prints "T" then prints the sixth character since we start counting at 0 hence prints "Ti" (note that space is also a character).

Hope this helps.

No sadly.
You can change your e-mail, profile picture, but that's about it.
I didn't see an option to change your name.

Write a program that accepts three decimal numbers as input and outputs their sum​
Sophie [7]

Answer:

sum = 0.0

for i in range(0,3):

   sum += float(input("Enter a decimal number to sum: "))

print ("Sum: ", sum)

*** Sample Input ***

Enter a decimal number to sum: 1.1

Enter a decimal number to sum: 2.2

Enter a decimal number to sum: 3.3

*** Sample Output ***

Sum:  6.6

Explanation:

For this problem, a method was devised in python to create the sum of three individual decimal numbers.

The first line of code, <em>sum = 0.0</em>, initializes a variable to the float type in which we will store the value of our sum.  Note, it is initialized to 0.0 to start from a value of 0 and be considered a float.

The second line of code, <em>for i in range(0,3):</em>  is the creation of a for loop control structure.  This will allow us to repeat a process 3 amount of times using the iterator i, from value 0 to 3 in this case.  Note, 0 is inclusive and 3 is exclusive in the python range.  This means the for loop will iterate with, i=0, i=1, and i=2.

The third line of code, <em>sum += float(input("Enter a decimal number to sum: "))</em>  is simply asking the user for a number, taking that input and converting it from a string into a float, and then summing the value with the previous value of sum and saving that into sum.

The fourth line of code, <em>print ("Sum: ", sum)</em> is simply displaying the final value that was calculated by adding the three user inputs together which were stored into the variable <em>sum</em>.

Cheers.
