关于TypeError: strptime() argument 1 must be str, not bytes解析

这个错误是由于你将字节字符串作为参数传递给了 `strptime()` 函数，而该函数期望的是一个普通的字符串。要解决这个问题，你需要将字节字符串转换为普通字符串。你可以使用 `.decode()` 方法将字节字符串解码为字符串，然后再将其传递给 `strptime()` 函数。例如：

byte_string = b"2022-01-01"
string = byte_string.decode()
date = datetime.datetime.strptime(string, "%Y-%m-%d")

这里，我们使用 `.decode()` 方法将字节字符串 `byte_string` 解码为普通字符串 `string`，然后将其传递给 `strptime()` 函数进行日期解析。确保你正确设置日期的格式化字符串以匹配你的日期格式。

TypeError: strptime() argument 1 must be str, not Series

This error occurs when you try to pass a Pandas Series object as the argument for the strptime() method. The strptime() method is used to convert a string into a date object, but it requires a string as input, not a Series object.

To resolve this error, you can convert the Series object into a string before passing it to the strptime() method. You can do this using the .astype() method, which allows you to convert the data type of a Pandas Series.

For example:

import pandas as pd
from datetime import datetime

# create a sample Series object
dates = pd.Series(['2022-01-01', '2022-01-02', '2022-01-03'])

# convert the Series to a string using .astype()
date_str = dates.astype(str)

# use strptime() to convert the string to a date object
date_obj = datetime.strptime(date_str, '%Y-%m-%d')

In this example, we first convert the dates Series object to a string using the .astype() method. We then pass the resulting string to the strptime() method to convert it into a date object.

TypeError: strptime() argument 1 must be str, not None

这个错误通常发生在使用datetime模块中的strptime()函数时，第一个参数传递了None。

请确保第一个参数是一个字符串，例如：

import datetime

date_string = "2021-06-01"
date_object = datetime.datetime.strptime(date_string, "%Y-%m-%d")
print(date_object)

如果你传递了None作为第一个参数，请检查代码中的变量和函数，确保它们都有正确的值。
