Activity 7.19.1.

Fix the code so that only “meow” is printed.

Activity 7.19.2.

Arrange the blocks on the right side so that only "meow" is printed.

sentence = "The cat goes meow."
---
s2 = sentence[13:17]
---
s2 = sentence[0:17] #paired
---
print(s2)

Activity 7.19.3.

Create a function named count that accepts a string and a letter as arguments, then returns the count of that letter in the string. For example, if the function call was count("banana", "a") it would return 3. Hint: use the count method.

Activity 7.19.4.

Create a function named count that accepts a string and a letter as arguments, then returns the count of that letter in the string. For example, if the function call was count("banana", "a") it would return 3. Hint: use the count method.

def count(str, letter):
---
def count(str, letter) #paired
---
    return str.count(letter)
---
    return count(letter) #paired

Activity 7.19.5.

In Robert McCloskey’s book Make Way for Ducklings, the names of the ducklings are Jack, Kack, Lack, Mack, Nack, Ouack, Pack, and Quack. The following loop tries to output these names in order. Of course, that’s not quite right because Ouack and Quack are misspelled. Can you fix it?

Activity 7.19.6.

In Robert McCloskey’s book Make Way for Ducklings, the names of the ducklings are Jack, Kack, Lack, Mack, Nack, Ouack, Pack, and Quack. The following loop tries to output these names in order. Of course, that’s not quite right because Ouack and Quack are misspelled. Can you put the blocks in order to fix it?

prefixes = "JKLMNOPQ"
suffix = "ack"
---
for letter in prefixes:
---
    if letter == 'O' or letter == 'Q':
        print(letter + "u" + suffix)
---
    if letter == 'o' or letter == 'Q':
        print(letter + "u" + suffix) #paired
---
    else:
        print(letter + suffix)

Activity 7.19.7.

Write code to print out the statement “Hi my name is Bob2” using only string methods or string slicing. You must get every part of the new string from the given strings, not by using string literals. Name the final string statement.

Activity 7.19.8.

Create code to print out the statement “Hi my name is Bob2” using only string methods or string slicing. You must get every part of the new string from the given strings, not by using string literals. Name the final string statement.

s1 = "hi"
s2 = "My name is Bob, and he and I love to eat ham."
---
statement = s1.capitalize() + s2[2:3] + s2[0:1].lower() + s2[1:14] + str(len(s1))
---
statement = s1.capitalize() + s2.[0:13] + len(s1) #paired

Activity 7.19.9.

Write a program that asks for user input and prints their input in all lowercase, as well as the length of their string.

Activity 7.19.10.

Create a program that asks for user input and prints their input in all lowercase, as well as the length of their string.

user_input = input("Enter a string: ")
---
print(user_input.lower() + " " + str(len(user_input)))
---
print(user_input.lower() + " " + len(user_input)) #paired

Activity 7.19.11.

Arrange the blocks to fix the code so that it prints “Hi” instead of “hi”.

s1 = "hi"
---
s1 = s1.capitalize()
---
s1.capitalize() #paired
---
print(s1)

Activity 7.19.12.

Arrange the blocks to evaluate the length of the string “I like green eggs”, store it in a variable named length, and print it, so that it prints “The length is 17”.

sentence = "I like green eggs"
---
length = len(sentence)
---
length = str(sentence) #paired
---
print("The length is " + str(length))

Activity 7.19.13.

Arrange the blocks to use find and string slicing to extract the portion of string after the colon character and convert it into a floating point number called num.

string = "X-DSPAM-Confidence: 0.8475"
---
colonpos = string.find(':')
---
colonpos = string.find(".") #paired
---
num = float(string[colonpos+1:])
---
num = float(string[colonpos:]) #paired
---
print(num)

Activity 7.19.14.

Arrange the blocks to define a function numDigits that returns the number of digits in an integer n.

def numDigits(n):
---
def numDigits(n) #paired
---
    return len(str(n))
---
    return len(n) #paired

Activity 7.19.15.

Arrange the blocks to ask the user for their name and print the first letter of their name in lowercase.

prompt = "What is your name?"
name = input(prompt)
---
first = name[0]
---
lowerFirst = first.lower()
---
lowerFirst = first.upper() #paired
---
print(lowerFirst)
