NumPy: Array converted to a float type

NumPy: Array Object Exercise-7 with Solution

Write a NumPy program to convert an array to a float type.

Python NumPy: Array converted to a float type

Sample Solution:-

Python Code:

import numpy as np
import numpy as np
a = [1, 2, 3, 4]
print("Original array")
print(a)
x = np.asfarray(a)
print("Array converted to a float type:")
print(x)

Sample Output:

Original array                                                          
[1, 2, 3, 4]                                                            
Array converted to a float type:                                        
[ 1.  2.  3.  4.]

Python: Tips of the Day

Python: Inserting if statements using conditional list comprehensions

x = [1, 2, 3, 4, 5, 6]
result = []
for idx in range(len(x)):
    if x[idx] % 2 == 0:
        result.append(x[idx] * 2)
    else:
        result.append(x[idx])
result

Output:

[1, 4, 3, 8, 5, 12]
[(element * 2 if element % 2 == 0 else element) for element in x]

Output:

[1, 4, 3, 8, 5, 12]
[element * 2 for element in x if element % 2 == 0]

Output:

[4, 8, 12]
