为什么我的ipython笔记本没有显示结果？

Question

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import numpy as np
%matplotlib inline
%pylab inline
pylab.rcParams['figure.figsize'] = (12, 12)
import seaborn as sns
all_sets=pd.read_csv(r"C:\Users\champion\Desktop\ch02\AllSets-x.json")
df_list=[]
for i in all_sets.columns.values:
    deck=allset[str(i)]["card"]
    df = pd.DataFrame(deck)
    df_list.append(df)
all_cards = pd.concat(df_list)
all_cards.cmc.fillna(0)
all_cards.reset_index(inplace=True)
all_cards.columns.values

当我说出我的代码时，结果没有显示出来。 而ipython笔记本右边有IN [*]。
