的方法
Python Pandas Series.head()
函式從開頭返回選定的值。
pandas.Series.head()
的語法
Series.head(n=5)
引數
n |
它是一個整數引數。它指定了要選擇和返回的值的數量。 |
返回值
它返回 Series
的前 n
個值。
示例程式碼:Series.head()
方法返回 Series
的前 5 個值
import pandas as pd
series = pd.Series([ 'Rose', 'Jasmine', 'Lili', 'Tulip', 'Hibiscus', 'Sun Flower', 'Orchid', 'Carnation','Irises', 'Gardenias'])
print("The Original Series is: \n")
print(series)
series1 = series.head()
print("The First Five Values of Series From Start are: \n")
print(series1)
輸出:
The Original Series is:
0 Rose
1 Jasmine
2 Lili
3 Tulip
4 Hibiscus
5 Sun Flower
6 Orchid
7 Carnation
8 Irises
9 Gardenias
dtype: object
The First Five Values of Series From Start are:
0 Rose
1 Jasmine
2 Lili
3 Tulip
4 Hibiscus
dtype: object
我們沒有傳入任何引數,因為 n
的預設值是 5。函式已經返回了給定 Series
的前五個值。
示例程式碼:Series.head()
方法返回 Series
的前 7 個值
import pandas as pd
series = pd.Series([ 'Rose', 'Jasmine', 'Lili', 'Tulip', 'Hibiscus', 'Sun Flower', 'Orchid', 'Carnation','Irises', 'Gardenias'])
print("The Original Series is: \n")
print(series)
series1 = series.head(7)
print("The First Seven Values of Series From Start are: \n")
print(series1)
輸出:
The Original Series is:
0 Rose
1 Jasmine
2 Lili
3 Tulip
4 Hibiscus
5 Sun Flower
6 Orchid
7 Carnation
8 Irises
9 Gardenias
dtype: object
The First Seven Values of Series From Start are:
0 Rose
1 Jasmine
2 Lili
3 Tulip
4 Hibiscus
5 Sun Flower
6 Orchid
dtype: object
我們已經通過 n=7
。該函式返回了給定 Series
的前七個值。
示例程式碼:Series.head()
返回空 Series
的方法
import pandas as pd
series = pd.Series([ 'Rose', 'Jasmine', 'Lili', 'Tulip', 'Hibiscus', 'Sun Flower', 'Orchid', 'Carnation','Irises', 'Gardenias'])
print("The Original Series is: \n")
print(series)
series1 = series.head(0)
print("The Empty Series is: \n")
print(series1)
輸出:
The Original Series is:
0 Rose
1 Jasmine
2 Lili
3 Tulip
4 Hibiscus
5 Sun Flower
6 Orchid
7 Carnation
8 Irises
9 Gardenias
dtype: object
The Empty Series is:
Series([], dtype: object)
函式返回一個空序列。
