df['column_name'] = pd.to_datetime(df['column_name'], format='%Y-%m-%d %H:%M:%S') 完成上述步骤后,目标列的数据类型将从“object”转换为datetime,可以使用datetime类型的方法和属性进行日期和时间的操作和分析。 示例代码: 代码语言:txt 复制 import pandas as

Pandas Time Series: Exercise-18 with Solution Write a Pandas program to create a time series object with a time zone. Sample Solution: Python Code : importpandasaspdprint("Timezone: Europe/Berlin:")print("Using pytz:")date_pytz=pd.Timestamp('2019-01-01',tz='Europe/Berlin')print(date_py...
同样,我们可以使用fromtimestamp(). 这是一个 datetime 以时间戳(浮点格式)为参数并返回一个 datetime 对象的函数,如下所示: #import datetimefrom datetime import datetimetimestamp = 1572014192.8273#convert timestamp to datetime objectdt_object = datetime.fromtimestamp(timestamp)print("dt_object:", dt_o...

在这个示例中,pd.to_datetime(df['date_str'])将date_str列中的字符串转换为datetime对象,并将结果赋值给新的列date_time。 综上所述,当你遇到'dataframe' object has no attribute 'to_datetime'这个错误时,应该检查你的代码,确保你是在正确地使用pandas.to_datetime()函数,而不是尝试将其作为DataFrame对象的...
