Build your fundamental Python concepts with these 5 Examples

Getting started with Python: 

• Download and Pre-install Python and PyCharm (Free, open-source) to practice the examples below.

To create a new project in PyCharm - Right Click 'new' on your Project Folder of the left navbar you created. Next, give your file a name and click 'ok'. To run your file, click 'run' located at the top menu bar. 

Example 1: Print "Hello World"

print("Hello World")

Output: Hello World

Example 2: Drawing a Shape

print("   /|")

print("  /  |")

print(" /   |")

print("/__ |")

Output: 

    /|

  /  |

 /   |

/__ |

*In Python, order of the instruction matters.

Example 3: Variable and Data Types

print("There once was a man named Bob")

print("He was 70 years old.")

print("He really liked the name Bob")

print("but didn't like being 70.")

Output:

There once was a man named Bob

He was 70 years old.

He really liked the name Bob

but didn't like being 70.

character_name = "Bob"

character_age = "70"

is_male = True

print("There once was a man named " + character_name +", ")

print("He was " + character_name + " years old. ")

print("He really liked the name" + character_name +", ")

print("but didn't like being " + character_age +".")

Output:

There once was a man named Bob, 

He was Bob years old. 

He really liked the nameBob, 

but didn't like being 70.

Example 4: Working with Strings

print("Semiconductor\nBlog")

Output:

Semiconductor

Blog

phrase = "Semiconductor Blog"

print(phrase)

Output:

Semiconductor Blog

Concatenation - Process of taking a string and appending another string upon to it.

phrase = "Semiconductor Blog"

print(phrase + " is cool")

Output:

Semiconductor Blog is cool

phrase = "Semiconductor Blog"

print(phrase.lower())

Output:

semiconductor blog

phrase = "Semiconductor Blog"

print(phrase.upper())

Output:

SEMICONDUCTOR BLOG

phrase = "Semiconductor Blog"

print(phrase.isupper())

Output:

False

phrase = "Semiconductor Blog"

print(phrase.upper().isupper())

Output:

True

phrase = "Semiconductor Blog"

print(len(phrase))

Output:

18

phrase = "Semiconductor Blog"

                 0123...................

print(phrase[0])

Output: 

S

phrase = "Semiconductor Blog"

print(phrase[3])

Output:

i

phrase = "Semiconductor Blog"

print(phrase.index("i"))

Output: index function > passing a parameter

3

phrase = "Semiconductor Blog"

print(phrase.index("Blog"))

Output: index function > passing a parameter

15

phrase = "Semiconductor Blog"

print(phrase.index("x"))

Output: index function > passing a parameter

Value Error

phrase = "Semiconductor Blog"

print(phrase.replace("Semiconductor", "SemiSaga"))

Output: 

SemiSaga Blog

Example 5: Working with Numbers

print(2)

Output:

2

print(2.32)

Output:

2.32

print(-2)

Output:

-2

print(2 + 4.5)

Output:

6.5

print(3 * 4)

Output:

12

print(3 * 4 + 5)

Output:

17

print(3 * (4 + 5))

Output:

27

print(10 % 3)

Output: % is the modulus => remainder

1

my_num = 5

print(my_num)

Output:

5

my_num = 5

print(str(my_num) + " my favorite number")

Output:

5 my favorite number

my_num = -5

print(abs(my_num))

Output:

5

my_num = 5

print(pow(4, 6))

Output:

4096

my_num = -5

print(max(4, 6))

Output:

6

my_num = 5

print(min(4, 6))

Output:

4

my_num = -5

print(round(3.2))

Output:

3

from math import *

my_num = -5

print(floor(3.7))

Output:

3

from math import *

my_num = -5

print(sqrt(36))

Output:

6.0
