如何使用字典中的键作为索引创建 pandas DataFrame？ [蟒蛇，熊猫]

Question

Let's say I have this dictionary:

d = {'Name1': (33, 'String1'), 'Name2': (59, 'String2')}

And all I want to do is print a DataFrame with pandas, where the index are my keys and I'll have two columns where I'll put the values of the respective keys in it.

Thanks a lot in advance!

Answer 1

if you want the keys of the dictionary to be the index then you can do this:

d = {'Name1': (33, 'String1'), 'Name2': (59, 'String2')}
df=pd.DataFrame(d.values(),index=d.keys())
print(df)

output:

        0        1
Name1  33  String1
Name2  59  String2

Answer 2

pd.DataFrame.from_dict(d, orient='index', columns=['column A', 'column B'])

Answer 3

Have you tried to do this. Just create the dataframe using d and then transpose the dataframe.

import pandas as pd
d = {'Name1': (33, 'String1'), 'Name2': (59, 'String2')}
df=pd.DataFrame(d).T
df = df.rename(columns={0:'column1',1:'column2'})
print (df)

If you want a single line, then it is:

df=pd.DataFrame(d).T.rename(columns={0:'column1',1:'column2'})

The output will be as follows:

      column1  column2
Name1      33  String1
Name2      59  String2
