1. Generating Numbers
Create a function generateNumbers(num) that takes in a positive number as argument and returns a list of number from 0 to that number inclusive. Note: The function range(5) will return a list of number [0, 1, 2, 3, 4].
def generateNumber(num):
new=[]
num1=num+1
for i in range(num1):
new.append(i)
return new
2. Generating Numbers II
Create a function generateNumbers(start, end) that takes in two numbers as arguments and returns a list of numbers starting from start to the end number (inclusive) specified in the arguments. Note: The function range(x, y) can takes in 2 arguments. For example, range(1, 5) will return a list of numbers [1,2,3,4].
def generateNumber(start, end):
new=[]
end1=end+1
for i in range(start,end1):
new.append(i)
return new
3.Generating Numbers III
Create a function generateNumbers(start, end, step) that takes in three numbers as arguments and returns a list of numbers ranging from start to the end number (inclusive)and skipping numbers based on the step specified in the arguments. Note: The function range(x, y, z) can takes in 3 arguments. For example, range(1, 11, 2) will return a list of numbers [1,3,5,7,9].
def generateNumber(num1,num2,num3):
if num3<0:
num4=num2-1
else:
num4=num2+1
new=[]
for i in range(num1,num4,num3):
new.append(i)
return new
4. Adding A Range Of Numbers
Create a function addNumbers(num) that takes in a positive number as argument and returns the sum of all the number between 0 and that number (inclusive).
def addNumbers(num):
num1=num+1
add=0
for i in range(num1):
add+=i
return add
5. Adding A Range Of Numbers II
Create a function addNumbers(start, end) that takes in two positive numbers as arguments and returns the sum of all the number between the start and end number (inclusive).
def addNumbers(num1,num2):
num3=num2+1
add=0
for i in range(num1,num3):
add+=i
return add
6. Adding Even Numbers
Create a function addEvenNumbers(start, end) that takes in two positive numbers as arguments and returns the sum of all the even numbers between the start and end number (inclusive). Note: x % 2 returns 0 if x is an even number.
def addEvenNumbers(num1,num2):
if num1%2==0:
num11=num1
else:
num11=num1+1
add=0
for i in range(num11,num2+1,2):
add+=i
return add
7. Using ‘Continue’ To Skip Code Within A Loop
Making use of the ‘continue’ statement to skip the rest of execution within a loop block for current iteration, and move to the next iteration.
# Insert 'continue' in following code so that it returns a
# string with no vowels.
def skipVowels(word):
novowels = ''
for ch in word:
if ch.lower() in 'aeiou':continue
novowels+=ch
return novowels
8. Using ‘Break’ To Abort A For/While Loop
Making use of the ‘break’ statement to abort a for/while loop, and move to the code after the loop block .
# insert 'break' in following code so that the comment
# after '#' (including '#') are stripped.
def stripComment(sentence):
codeonly = ""
for ch in sentence:
if ch == '#':break
codeonly+=ch
return codeonly
9. Create Set From A List
Create a function genSet() that takes in a list of numbers and returns a sorted set.
def genSet(nums):
numbers=set(nums)
return sorted(numbers)
10. Using ‘For’ To Traverse String.[MCQ]
Different ways of traversing strings using ‘for’ loop
Question:
[MCQ] Which of the following ‘for’ loops does not give the same output?
** greetings = ‘Hello World’
for x in greetings:
print x,
** greetings = ‘Hello World’
for x in range(len(greetings)):
print greetings[x],
** greetings = ‘Hello World’
for x in greetings:
print greetings[x],
** greetings = ‘Hello World’
for x in range(len(greetings), 0, -1):
print greetings[-x],
** None of the above.
11. Sum Of Digits
Write a function sumOfDigit(number) that takes in a number as argument and returns the sum of the individual digit in the number.
def sumOfDigit(num):
num1=str(num)
a=len(num1)
i=0
add=0
for i in range(a):
add+=int(num1[i])
return add
