使用 NumPy 功能创建熊猫系列
原文:https://www . geeksforgeeks . org/create-pandas-series-using-numpy-functions/
Pandas Series 是一个一维标记数组，能够保存任何类型的数据(整数、字符串、浮点、python 对象等)。).
让我们看看如何使用不同的numpy 功能创建熊猫系列。
代码#1: 使用 numpy.linspace()
# import pandas and numpy
import pandas as pd
import numpy as np
# series with numpy linspace()
ser1 = pd.Series(np.linspace(3, 33, 3))
print(ser1)
# series with numpy linspace()
ser2 = pd.Series(np.linspace(1, 100, 10))
print("\n", ser2)
输出:
代码#2: 使用 np.random.normal() 和rand()方法。
# import pandas and numpy
import pandas as pd
import numpy as np
# series with numpy random.normal
ser3 = pd.Series(np.random.normal())
print(ser3)
# series with numpy random.normal
ser4 = pd.Series(np.random.normal(0.0, 1.0, 5))
print("\n", ser4)
# series with numpy random.rand
ser5 = pd.Series(np.random.rand(10))
print("\n", ser5)
输出:
代码#3: 使用 numpy.repeat()
# import pandas and numpy
import pandas as pd
import numpy as np
# series with numpy random.repeat
ser = pd.Series(np.repeat(0.08, 7))
print("\n", ser)
输出:
