CS50 — A Taste of Python

Harvard Mario’s Challenge Solver \o/ #PurePythonSeries — Episode #10

Hi! Let’s have fun! Just that! Let’s go to the amusement park and play with python?

This time, I’m taking the CS50 — from Harvard University.

Solving CS50 — Pset1 — Exercise — Class 1

Be welcome!

Let’s get started!

We need for loop:

for(i = 0; i < n; i++):
    print('#')

File "<ipython-input-82-101f42122273>", line 1
    for(i = 0; i < n; i++):
          ^
SyntaxError: invalid syntax

Opps! In Python, there is not C like syntax for(i=0; i<n; i++) but you use for in n.

If you want to automate a specific repetitive task or prevent yourself from writing repetitive code in your programs, using a loop is the best option for that.

Loops are a set of instructions that run repeatedly until a condition is met.

To solve these problems, we surely need one:

Create in Python this Mario`s Pyramid in console…

There are two types of loops built into Python:

for loops:

for iterator in sequence:
    execute expression

while loops:

while condition:
    execute expression

Let’s try it the Pythonic way:

for number in range(10, 21):
   if number % 2 == 0:
   print("The number", number, "is even")

The number 10 is even
The number 12 is even
The number 14 is even
The number 16 is even
The number 18 is even
The number 20 is even

Here is # Tuple Unpacking:

x = [(1,2),(3,4),(5,6)]
for item in x:
   print(item)

(1, 2)
(3, 4)
(5, 6)

Or:

for (a,b) in x:
   print(a)

1
3
5

Or even:

for a,b in x:
   print(a+1, b+1)

2 3
4 5
6 7

Let’s review # Python end parameter in print() too:

print("Welcome to" , end = ' ')
print("GeeksforGeeks", end = ' ')

Welcome to GeeksforGeeks

It ends line by space instead of \n.

Look here we did not call parameter in the first print:

print("Welcome to")
print("GeeksforGeeks", end = ' ')

Welcome to
GeeksforGeeks

MARIO'S PYRAMID

for inside for

# Mario's pyramid upside down :)

for i in range(0, 4):
   for j in range(0,4-i):
      print('#', end=" ")

    print('')

# # # # 
# # # 
# # 
#

Now :

# Mario's pyramid left alignment:)

for i in range(0, 4):
   for j in range(0,i+1):
      print('#', end=" ")

    print('')

# 
# # 
# # # 
# # # #

Just while loop to ask and for to print

# Mario's Pyramid right alignment:)
# asks numbers between 0 and 8

print('Height: ', end=' ')
h = int(input());

while(h<0 or h > 8):
   print("That is an invalid input")
   print('Height: ', end='')
   h = int(input())

for i in range(h):
   print(" "*(h-i)+"#"*(i+1))

Height:  4
    #
   ##
  ###
 ####

A different for:

# The counter's range is toyed with here
for i in range(1, h + 1):
# The "i + 1" is removed 
print(" " * (h - i) + "#" * i)

   #
  ##
 ###
####

Step by step solution:

#first:

# Printing space

h=4
for i in range(h):
   print(" "*(h-i));

Single Hash by line:

# Printing 1 hash at the end of spaces

h=4
for i in range(h):
   print(" "*(h-i)+"#")

    #
   #
  #
 #

Final result:

# Printing the whole Mari's Pyramid

h=4
for i in range(h):
   print(" "*(h-i)+"#"*(i+1))

    #
   ##
  ###
 ####

Double Pyrami, using while + for:

print('Height: ', end='');

h = int(input());

while(h<0 or h > 8):
   print("That is an invalid input")
   print('Height: ', end='');
   h = int(input());

for i in range(h):
   print(" "*(h-i)+"#"*(i+1)+ "  "+"#"*(i+1));

Height: 4
    #  #
   ##  ##
  ###  ###
 ####  ####

Enough o/

print("That's it, folks. This is CS50! Harvard course, man \o/")

That's it, folks. This is CS50! Harvard course, man \o/

That’s all, folks!

See you soon o/

Bye!
