为什么我不能添加字典？答案

【问题标题】：Why I can't I add dictionaries?为什么我不能添加字典？

【问题描述】：

我有两个字典，我想合并它们，但由于某种原因它不起作用。这是代码：

dict1= {"Player":["Virat Kohli","Jasprit Bumrah","Saurabh Netravalkar"],
    "Role":["Batsman","Bowler", "Bowler"],
    "Team":["India", "India", "USA"]}
dict2 = {"Monank Patel","Batsman","USA"}
dict1.update(dict2)
pd.DataFrame(dict1)

非常感谢！！

【问题讨论】：

dict2 不是字典

我认为这就是你想要做的：

dict1= {"Player":["Virat Kohli","Jasprit Bumrah","Saurabh Netravalkar"],
    "Role":["Batsman","Bowler", "Bowler"],
    "Team":["India", "India", "USA"]}
dict2 = ["Monank Patel","Batsman","USA"]
dict1['Player'].append("Monank Patel")
dict1['Role'].append("Batsman")
dict1['Team'].append("USA")
df = pd.DataFrame(dict1)
print(df)

                Player     Role   Team
0          Virat Kohli  Batsman  India
1       Jasprit Bumrah   Bowler  India
2  Saurabh Netravalkar   Bowler    USA
3         Monank Patel  Batsman    USA

编辑：

dict1= {"Player":["Virat Kohli","Jasprit Bumrah","Saurabh Netravalkar"],
    "Role":["Batsman","Bowler", "Bowler"],
    "Team":["India", "India", "USA"]}
list2 = [["Monank Patel","Batsman","USA"], ["Monank Patel","Batsman","USA"]]

df = pd.DataFrame(dict1)
df = df.append(pd.DataFrame(list2, columns=df.columns))
print(df)

                Player     Role   Team
0          Virat Kohli  Batsman  India
1       Jasprit Bumrah   Bowler  India
2  Saurabh Netravalkar   Bowler    USA
0         Monank Patel  Batsman    USA
1         Monank Patel  Batsman    USA

感谢您的澄清！另外，如果我有 70 行这样的行，有没有比硬编码更简单的方法来做到这一点？
