如何将pandas整型分钟数据框列转换为HH:MM格式？

import pandas as pd
from datetime import datetime

# 创建示例数据框
data = {'minutes': [90, 120, 150, 180]}
df = pd.DataFrame(data)

# 将minutes列转换为整型数据类型
df['minutes'] = df['minutes'].astype(int)

# 定义转换函数
def convert_to_hh_mm(minutes):
    hours = minutes // 60
    mins = minutes % 60
    time_str = datetime.strptime(f"{hours}:{mins:02}", "%H:%M").strftime("%H:%M")
    return time_str

# 使用apply方法进行转换
df['time'] = df['minutes'].apply(convert_to_hh_mm)

print(df)

   minutes   time
0       90  01:30
1      120  02:00
2      150  02:30
3      180  03:00
