Bin values based on ranges with pandas [duplicate]

Solution 1:

In order to bucket your series, you should use the pd.cut() function, like this:

df['bin'] = pd.cut(df['1'], [0, 50, 100,200])

         0    1        file         bin
0  person1   24     age.csv     (0, 50]
1  person2   17     age.csv     (0, 50]
2  person3   98     age.csv   (50, 100]
3  person4    6     age.csv     (0, 50]
4  person2  166  Height.csv  (100, 200]
5  person3  125  Height.csv  (100, 200]
6  person5  172  Height.csv  (100, 200]

If you want to name the bins yourself, you can use the labels= argument, like this:

df['bin'] = pd.cut(df['1'], [0, 50, 100,200], labels=['0-50', '50-100', '100-200'])

         0    1        file      bin
0  person1   24     age.csv     0-50
1  person2   17     age.csv     0-50
2  person3   98     age.csv   50-100
3  person4    6     age.csv     0-50
4  person2  166  Height.csv  100-200
5  person3  125  Height.csv  100-200
6  person5  172  Height.csv  100-200
