The problem of converting a dictionary to a DataFrame Note that the default dictionary is '1': [1,2,3], not '1': 1. That is, the dictionary will be converted to a DataFrame in the form of a list later.

Convert dict d = {'A':0}to DataFrame,
first of all, the syntax format of DataFrame should be:

import pandas as pd
df = pd.DataFrame({'A':[0]})#'A'是columns，对应的是list

• 1
• 2

output:

   A
0  0

• 1
• 2

But if it is:

df = pd.DataFrame({'A':0})#直接输入dict

• 1

will report an error

ValueError: If using all scalar values, you must pass an index

• 1

Solution 1:
Specify index

pd.DataFrame({'A':0}，index=[0])

• 1

Solution 2:
Put the dictionary in a list

pd.DataFrame([{'A':0},{'A':1}])

• 1

output:

   A
0  0
1  1
