You can use labels to pd.cut() as well. The following example contains the grade of students in the range from 0-10. We're adding a new column called 'grade_cat' to categorize the grades.

bins represent the intervals: 0-4 is one interval, 5-6 is one interval, and so on The corresponding labels are "poor", "normal", etc

bins = [0, 4, 6, 10]
labels = ["poor","normal","excellent"]
student['grade_cat'] = pd.cut(student['grade'], bins=bins, labels=labels)
