Python Pandas DataFrame.to_dict()
function converts the given DataFrame to a dictionary.
Syntax of pandas.DataFrame.to_dict()
:
DataFrame.to_dict(orient='dict',
into= < class 'dict' >)
Parameters
orient |
This parameter determines the type of the dictionary. For example, it can be a dictionary of series or list. It has six options. These are dict , list , Series , split , records , and index . |
into |
It is a class parameter. We can pass an actual class or its instance as a parameter. |
Return
It returns the dictionary that represents the passed Dataframe.
Example Codes: DataFrame.to_dict()
Method to Convert the DataFrame Into Dictionary of Dictionaries
To convert a DataFrame into a dictionary of dictionaries, we will pass no parameters.
import pandas as pd
dataframe=pd.DataFrame({'Attendance': {0: 60, 1: 100, 2: 80,3: 78,4: 95},
'Name': {0: 'Olivia', 1: 'John', 2: 'Laura',3: 'Ben',4: 'Kevin'},
'Obtained Marks': {0: 90, 1: 75, 2: 82, 3: 64, 4: 45}})
print("The Original Data frame is: \n")
print(dataframe)
dataframe1 = dataframe.to_dict()
print("The Dictionary of Dictionaries is: \n")
print(dataframe1)
Output:
The Original Data frame is:
Attendance Name Obtained Marks
0 60 Olivia 90
1 100 John 75
2 80 Laura 82
3 78 Ben 64
4 95 Kevin 45
The Dictionary of Dictionaries is:
{'Attendance': {0: 60, 1: 100, 2: 80, 3: 78, 4: 95}, 'Obtained Marks': {0: 90, 1: 75, 2: 82, 3: 64, 4: 45}, 'Name': {0: 'Olivia', 1: 'John', 2: 'Laura', 3: 'Ben', 4: 'Kevin'}}
The function has returned the dictionary of dictionaries.
Example Codes: DataFrame.to_dict()
Method to Convert the DataFrame Into Dictionary of Series
To convert a DataFrame into a dictionary of series, we will pass Series
as the orient
parameter.
import pandas as pd
dataframe=pd.DataFrame({'Attendance': {0: 60, 1: 100, 2: 80,3: 78,4: 95},
'Name': {0: 'Olivia', 1: 'John', 2: 'Laura',3: 'Ben',4: 'Kevin'},
'Obtained Marks': {0: 90, 1: 75, 2: 82, 3: 64, 4: 45}})
print("The Original Data frame is: \n")
print(dataframe)
dataframe1 = dataframe.to_dict('series')
print("The Dictionary of Series is: \n")
print(dataframe1)
Output:
The Original Data frame is:
Attendance Name Obtained Marks
0 60 Olivia 90
1 100 John 75
2 80 Laura 82
3 78 Ben 64
4 95 Kevin 45
The Dictionary of Series is:
{'Attendance': 0 60
1 100
2 80
3 78
4 95
Name: Attendance, dtype: int64, 'Obtained Marks': 0 90
1 75
2 82
3 64
4 45
Name: Obtained Marks, dtype: int64, 'Name': 0 Olivia
1 John
2 Laura
3 Ben
4 Kevin
Name: Name, dtype: object}
The function has returned the dictionary of series.
