Example
Read the values of two integer variables and then calculate and display the values of the quotient and remainder of their integer division.
print('Integer division of two integers a and b')
a = int(input('Enter value of a : '))
b = int(input('Enter value of b : '))
q = a // b
r = a % b
print('quotient : ', q)
print('remainder : ', r)
Example
Read the value of the radius of a circle then calculate and display the value of its area.
print('Calculate circle area')
r = float(input('Enter value of radius: '))
s = 3.14 * r ** 2
print(f'surface: {s:.2f}')
Example
Read a character and then display its Unicode code.
print('Print Unicode code of a character')
c = input('Enter a character: ')
u = ord(c)
print('code: ', u)
print(type(u))
Example
Read a Unicode code and then display the corresponding character.
print('Print character corresponding to Unicode code')
n = int(input('Enter a Unicode code: '))
c = chr(n)
print('caractère: ', c)
print(type(c))
Example
Using logical operators.
n = int(input('Enter an integer: '))
b = (n % 2) == 0
print(f'{n} even?: {b}')
c = (n % 3) == 0
d = (not b) and c
print(f'{n} is odd and multiple of 3?: {d}')
Example
Complex numbers.
import math
z = 1 + 2j
r = z.real
i = z.imag
print(f'real: {r} imag: {i}')
m = math.sqrt(r * r + i * i)
print(f'module: {m:.2f}')
c = z.conjugate()
print(f'conjugate: {c}')
Example
str data type.
greet = 'Hello'
print(type(greet))
print(greet)
print(greet[0])
print(greet[2:4])
print(greet[2:])
print(greet * 2)
print(greet + " World!")
Example
list data type.
data = ['Primes', 2, 3, 5, 7, 11]
print(type(data))
print(data)
print(data[0])
print(data[1:4])
print(data[2:])
data[0] = 'Prime numbers'
print(data)
more_data = [13, 17, 19]
data = data + more_data
print(data)
Example
dict data type.
data = {
'com' : 'Commercial',
'org' : 'Organization',
'net' : 'Network'
}
print(data)
print(data['com'])
print(data.keys())
print(data.values())
