# Demonstrate different ways to create strings

# Print a simple greeting
print('Hello world!')
print('Do you love Python?')
print('I really really love Python')
print("We can create a string using a single quote, double quote, or multiple quotes")
print('''It is possible to make a string with triple quote''')
print("""It is possible to make a string using triple quotes""")

Python Operators Usage

This script demonstrates the usage of various operators in Python.

Operators:

• Assignment operators (=)
• Arithmetic operators (+, -, *, /, %, //, **)
• Comparison operators (>, >=, <, <=, ==, !=, is, is not, in, not in)
• Logical operators (and, or, not)

Arithmetic operators

print('The addition of 4 and 3 is', 4 + 3)
print('The subtraction of 4 and 3 is', 4 - 3)
print('The product of 4 and 3 is', 4 * 3)
print('The division of 4 and 3 is', 4 / 3)
print('The remainder of 4 divided by 3 is', 4 % 3)
print('The floor division of 4 and 3 is', 4 // 3)
print('4 raised to the power of 3 is', 4 ** 3)

Variables and assignment operators

a = 4
b = 3
c = a + b
print(a)
print(b)
print(c)

Comparison operators

print(4 > 3)
print(4 >= 4)
print(4 >= 3)
print(4 < 3)
print(4 == 4)
print('The value here is', 4 != 4)
print(4 != '4')
print(4 == '4')
print(4 < 4)
print(4 is 4)
print(2 is not 4)
print(2 is not 2)
print('land' in 'Finland')
print('land' in 'Sweden')

Logical operators

print(4 > 3 and 2 < 3)
print(4 < 3 and 2 < 3)

print(4 > 3 or 2 < 3)
print(4 < 3 or 2 < 3)
print(4 < 3 or 2 > 3)

print(not 4 > 3)
print(not not 4 > 3)

print('land' not in 'Finland')
print(not True)
print(not False)

Python Data Types

This script provides examples and explanations for various data types in Python.

Data types covered:

• String: Represents text and can be created using single, double, or triple quotes.
• Numbers: Includes integers, floating-point numbers, and complex numbers.
• Boolean: Represents true or false values.
• List: An ordered collection of items.
• Tuple: An ordered, immutable collection of items.
• Set: An unordered collection of unique items.
• Dictionary: A collection of key-value pairs.

# String data type
# - Strings can be created using single, double, or triple quotes.
# - They can represent a single character or multiple pages of text.
l = 'a'
print(len(l))

word = 'Python'
print(word)
print(len(word))

sentence = 'Everyone here loves to learn Python programming'
print(len(sentence))
print(sentence.split())
print(len(sentence.split()))

Numbers data type

• Numbers include integers, floating-point numbers, and complex numbers.

a = 4
print(a, type(a))

pi = 3.14
print(pi, type(pi))

c = 1 + 2j
print(c, type(c))

Boolean data type

• Represents true or false values.
• Used in logical operations.

print(print(type(True)))
print(print(type(False)))

List data type

• An ordered collection of items.

nums = [1, 2, 3, 4, 5]
names = ['Asab', 'Eyob', 'Marta', 'John']

Tuple data type

• An ordered, immutable collection of items.

nums_tuple = (1, 2, 3, 4, 5)

Set data type

• An unordered collection of unique items.

nums_set = {1, 2, 3, 4, 5}

Dictionary data type

• A collection of key-value pairs.

fin_en = {
    'sana': 'word',
    'talo': 'house',
    'kirja': 'book'
}
