練習一、現有一份關於美劇《權力的遊戲》劇本的數據集，請解決以下問題：
在所有的數據中，一共出現了多少人物？
564個人物
方法一：直接統計
import pandas as pd
df = pd.read_csv(
r'D:\Desktop\pandas\Learning\joyful-pandas-master\data\Game_of_Thrones_Script.csv')
result = df['Name'].nunique()
print(df)
print(result)
輸出爲：
564
方法二：根據表長統計：
import pandas as pd
df = pd.read_csv(
r'D:\Desktop\pandas\Learning\joyful-pandas-master\data\Game_of_Thrones_Script.csv')
result = df['Name'].value_counts()
print(df)
print(result)
輸出爲：
tyrion lannister 1760
jon snow 1133
daenerys targaryen 1048
cersei lannister 1005
jaime lannister 945
...
robett glover 1
tribesmen of vale 1
bolton bannerman 1
watchman 1
officer 1
Name: Name, Length: 564, dtype: int64
2.以單元格計數（即簡單把一個單元格視作一句），誰說了最多的話？
import pandas as pd
df = pd.read_csv(
r'D:\Desktop\pandas\Learning\joyful-pandas-master\data\Game_of_Thrones_Script.csv')
result = df['Name'].value_counts()
man = result.index[0]
print(df)
print(result)
print(man)
輸出結果：
tyrion lannister 1760
jon snow 1133
daenerys targaryen 1048
cersei lannister 1005
jaime lannister 945
...
lord bolton 1
officer 1
eddision 1
pyattpree 1
rodrik cassal 1
Name: Name, Length: 564, dtype: int64
tyrion lannister
3.以單詞計數，誰說了最多的單詞？
import pandas as pd
df = pd.read_csv(
r'D:\Desktop\pandas\Learning\joyful-pandas-master\data\Game_of_Thrones_Script.csv')
print(df)
result1 = df.groupby('Sentence')['Name'].unique().apply(lambda x: x[0]).value_counts()
result1 = result1.index[0]
print(result1)
結果爲：tyrion lannister
練習二、現有一份關於科比的投籃數據集，請解決如下問題：
1.哪種action_type和combined_shot_type的組合是最多的？
import pandas as pd
df = pd.read_csv(
r'D:\Desktop\pandas\Learning\joyful-pandas-master\data\Kobe_data.csv')
print(df)
result1 = pd.Series(df['action_type']).value_counts()
result1 = result1.index[0]
print(result1)
結果爲：Jump Shot
2. 在所有被記錄的game_id中，遭遇到最多的opponent是一個支？
import pandas as pd
df = pd.read_csv(
r'D:\Desktop\pandas\Learning\joyful-pandas-master\data\Kobe_data.csv')
print(df)
result1 = df.groupby('game_id')['opponent'].unique().apply(lambda x: x[0]).value_counts()
result1 = result1.index[0]
print(result1)
結果爲：SAS
