Write the function lettersOnly(s) that takes in a string called s, and returns a string containing only the alphabetic character

Phantasy [73]

Answer:

The program to this question as follows:

Program:

def lettersOnly(s): #defining method lettersOnly

val="" #defining string variable that return value

for i in s: #defining loop to calculate value

if(i.isalpha()): #check condition that value is string

val=val+ i #add value

return val #return value

print(lettersOnly("data3base_ro1c3k5s")) #call method and print value

Output:

databaserocks

Explanation:

In the above python code, a method lettersOnly is declared that accepts a string variable "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.

In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.
At the last, the print method is used, which calls the lettersOnly method and prints its return value.

If you have downloaded this book's source code from the companion Web site, you will find a file named text.txt in the Chapter 1

Lubov Fominskaja [6]

Answer:

Explanation:

The following python code loops through each line within a file called text.txt and counts all the words, then it divides this count by the number of sentences in the text file. Finally, output the average number of words per sentence.

f = open("text.txt", "r")

all_words = 0

sentences = 0

for x in f:

list = x.split(' ')

all_words += len(list)

sentences += 1

average = all_words / sentences

print("There are an average of " + str(average.__round__()) + " words in each sentence.")
