检查数字的范围并在pandas数据帧中的新列中写入值

import pandas as pd

# 读取数据帧
df = pd.read_csv('data.csv')

def check_range(num):
    if num < 0:
        return 'Negative'
    elif num >= 0 and num <= 10:
        return '0-10'
    elif num > 10 and num <= 20:
        return '11-20'
    else:
        return 'Greater than 20'

# 在新列中写入值
df['Range'] = df['Number'].apply(check_range)
