让我们看看如何通过将摄氏温度列表转换成华氏温度来将其转换成 NumPy 数组。 将 Celcius 转换为 Farenhiet 的公式为:
feh = (9 * cel / 5 + 32)
方法 1 : 使用**numpy.array()**方法。
# importing the module
import numpy as np
# taking the celsius input
inp = [0, 12, 45.21, 34, 99.91]
# storing the input
# in numpy array
cel = np.array(inp)
print(f"Celsius {cel}")
# using formulae
feh = (9 * cel / 5 + 32)
# printing results
print(f"Fahrenheit {feh}")
输出:
Celsius [ 0\. 12\. 45.21 34\. 99.91]
Fahrenheit [ 32\. 53.6 113.378 93.2 211.838]
方法 2 : 使用**numpy.asarray()**方法。
# importing the module
import numpy as np
# taking the celsius input
inp = [0, 12, 45.21, 34, 99.91]
# storing the input
# in numpy array
cel = np.asarray(inp)
print(f"Celsius {cel}")
# using formulae
feh = (9 * cel / 5 + 32)
# printing results
print(f"Fahrenheit {feh}")
输出:
Celsius [ 0\. 12\. 45.21 34\. 99.91]
Fahrenheit [ 32\. 53.6 113.378 93.2 211.838]
方法三:使用**numpy.arange()**。
# importing the module
import numpy as np
# taking thecelsius input
inp = [0, 12, 45.21, 34, 99.91]
# arange will not directly
# convert into numpy array
cel = np.arange(5)
# the above code
# will give o/p as
# cel = [0, 1, 2, 3, 4]
cel = [i for i in inp]
# thus the input(inp)
# is stored in cel
# using list comprehension
print(f"Celsius {cel}")
# applying formulae
# using list comprehension
feh = [(9 * i / 5 + 32) for i in cel]
# printing results
print(f"Fahrenheit {feh}")
输出:
Celsius [ 0\. 12\. 45.21 34\. 99.91]
Fahrenheit [ 32\. 53.6 113.378 93.2 211.838]
