import pandas as pd
import numpy as np
df = pd.read_excel(r"")
bins = [0, 1 ,4,8,15, np.inf]
names = ['0-1','1-4','4-8','8-15','15+']
df1 = df.groupby(pd.cut(df['CREATEDDATE'],bins,labels=names))['casenumber'].size().reset_index(name='No_of_times_statuschanged')
CREATEDDATE No_of_times_statuschanged
0 0-1 2092
1 1-4 9062
2 4-8 12578
3 8-15 3858
4 15+ 0
I got the above data as out put but my expected should be range for month on month based on the cases per month .
expected output should be like
CREATEDDATE jan feb march april may june
0-1 1 2 3 4 5 6
1-4 3 0 6 7 8 9
4-8 4 6 3 0 9 2
8-15 0 3 4 5 8 9

Use crosstab with change CREATEDDATE to count for pd.cut and change order of column by subset by list of columns names:
#add another months if necessary
months = ["jan", "feb", "march", "april", "may", "june"]
bins = [0, 1 ,4,8,15, np.inf]
names = ['0-1','1-4','4-8','8-15','15+']
df1 = pd.crosstab(pd.cut(df['count'],bins,labels=names), df['CREATEDDATE'])[months]
print (df1)
CREATEDDATE jan feb march april may june
count
0-1 2 1 1 1 0 2
1-4 0 1 0 0 2 0
Another idea is use ordered categoricals:
df1 = pd.crosstab(pd.cut(df['count'],bins,labels=names),
pd.Categorical(df['CREATEDDATE'], ordered=True, categories=months))
print (df1)
col_0 jan feb march april may june
count
0-1 2 1 1 1 0 2
1-4 0 1 0 0 2 0
