Write Code Questions — Python for Everybody

Fix line 2 so that it prints “Hi” instead of “hi”.

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

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

        sentence = "The cat goes meow."
---
s2 = sentence[13:17]
---
s2 = [16:13]sentence
---
print(s2)

Write code to evaluate the length of the string “I like green eggs” and print it. Save the string as s1. It should print “The length is 17”.

Write code to evaluate the length of the string “I like green eggs” and print it. It should print “The length is 17”.

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

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

Take the following Python code that stores this string: string = "X-DSPAM-Confidence: 0.8475". Use find and string slicing to extract the portion of the string after the colon character and then use the float function to convert the extracted string into a floating point number called num.

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

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?

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

Write a function numDigits that will return the number of digits in an integer n.

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

Write code to print out the statement “Hi my name is Bob and I am 2” 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.lower()[0:3] + s2[3:14] + s2[22:29] + s2[4:6] + s2[2:3] + str(len(s1))
---
statement = s1.capitalize() + s2[7:8] + s2[5:6] + s2[1:2] + s2[3:15] + s2[22:29] + s2[4:6] + s2[2:3] + str(len(s1)) #paired
---
print(statement)

Write a program that asks a user for their name and from the input prints the first letter of their name in lowercase.

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

Write 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
