我在Python中编写了以下函数:
df = pd.DataFrame({'age': [32, 33, 33,34,44]})
def PROC_FREQ(dataset,arg1):
x= dataset.groupby(arg1)[arg1[0]].agg(({'Frequency':'count'}))
nombre=x.columns.tolist()[0]
x.rename(columns={nombre:'Freq'},inplace=True)
x['Pct']=round((x['Freq']/x.Freq.sum())*100,2)
x['Freq Acum'],x['Cumm Percent']=x.Freq.cumsum(),x.Pct.cumsum()
x.sort_values(arg1,ascending=[1],inplace=True)
pd.set_option('display.max_columns',500)
x=x.reset_index()
string_repr = x.to_string(index=False,justify='center').splitlines()
string_repr.insert(1, "-" * len(string_repr[0]))
out = '\n'.join(string_repr)
df_split = out.split('\n')
columns = shutil.get_terminal_size().columns
for i in range(len(df_split)):
print(df_split[i].center(columns))
及以下是调用该函数的代码:
PROC_FREQ(df,['age'])
及以下是函数的输出:
age Freq Pct Freq Acum Cumm Percent
-----------------------------------------
32 1 16.67 1 16.67
33 2 33.33 3 50.00
34 1 16.67 4 66.67
44 2 33.33 6 100.00
最后一行输出未正确对齐。
