在 python 中使用 .to_excel 写字典到 excel

Question

I have a dictionary with a couple floats, an int and a series all in one. I would like to write this to Excel all on the same sheet.

series = df5.copy()

dictionary = {'Avg':2.3534, 'Expected':series, 'Variance':1.01, 'Std. Dev': 1.78, '# of broken parts':300}

I have tried two different ways of writing these to Excel, one being straight to Excel where I receive an error saying dict has no.to_excel functionality, and the other method I tried the following:

dictionary.to_excel(writer,sheet_name = 'Break Date', index = False)

or

for key in dictionarys.keys():
    dictionary[key].to_excel(writer,sheet_name = key, index = False)

I would like the keys of the dictionary to be the title of the columns.

Desired output in Excel on same sheet:

Average  Expected   Variance    Std. Dev    # of broken parts
2.3534     2           1.01       1.78          300
           4
           2
           4

You can use the pandas library to convert your dictionary to a DataFrame and then write it to an Excel sheet.

First, convert the dictionary to a DataFrame:

df = pd.DataFrame(dictionary)

Then, use the to_excel method to write the DataFrame to an Excel sheet:

df.to_excel(writer, sheet_name='Break Date', index=False)

This will write the DataFrame to the sheet 'Break Date' in your Excel file, with the keys of the dictionary as the column names.

If you want to export all the key-value of the dictionary to the same sheet, you could use the following code:

df = pd.DataFrame.from_dict(dictionary, orient='index').transpose()
df.to_excel(writer, sheet_name='Break Date', index=False)

This will create a DataFrame where the keys of the dictionary are the columns name and the values of the dictionary are the values of the DataFrame and then export it to the excel sheet.
