Numpy using creating arrays

import numpy as np
arr = np.array([1, 2, 3])
print("Array with Rank : \n",arr)

Output:


Array with Rank :
[1 2 3]

[Program finished]

import numpy as np
arr = np.array([[1, 2, 3],[4, 5, 6]])
print("Array with Rank : \n", arr)

Output:
Array with Rank :
[[1 2 3]
[4 5 6]]

Numpy using arrays and tuple program



# Python program for
# Creation of Arrays
import numpy as np

# Creating a rank 1 Array
arr = np.array([1, 2, 3])
print("Array with Rank 1: \n",arr)

# Creating a rank 2 Array
arr = np.array([[1, 2, 3],
[4, 5, 6]])
print("Array with Rank 2: \n", arr)

# Creating an array from tuple
arr = np.array((1, 3, 2))
print("\nArray created using "
"passed tuple:\n", arr)

Area of triangle program

a = 5
b = 6
c = 7

# Uncomment below to take inputs from the user
# a = float(input('Enter first side: '))
# b = float(input('Enter second side: '))
# c = float(input('Enter third side: '))

# calculate the semi-perimeter
s = (a + b + c) / 2

# calculate the area
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5
print('The area of the triangle is %0.2f' %area)


Output
The area of the triangle is 14.70
