module 'pandas' has no attribute 'BDay'

抱歉,看起来你在尝试导入`pandas`库时出现了错误,`BDay`这个属性在较旧版本的`pandas`中已经不再存在。如果你需要判断工作日,你可以使用`pandas`的`BDay()`类配合`Calendar`类来实现。这里是一个更新的示例:
```python
from calendar import Calendar
def is_workday(date_string):
# 创建一个日历实例
cal = Calendar()
# 将字符串转换为日期对象
date = pd.to_datetime(date_string)
# 获取该日期对应的weekday(0-6,其中0表示周日)
weekday_num = date.weekday()
# 在大多数文化中,工作日通常是1(Monday)到5(Friday),6是周六,7是周日
if 1 <= weekday_num <= 5:
return True
else:
return False
# 测试示例
date_test = '2023-04-07'
print(is_workday(date_test)) # 输出结果,如果当天是工作日则返回True,否则返回False
```
请注意,这里的`weekday()`函数会直接给出0-6的整数,而不是像`BDay().onOffset()`那样返回布尔值。你需要自行处理周末。

module pandas has no attribute int
This error occurs when you try to use the `int` attribute on a pandas module, which does not exist. To resolve this issue, you should check your code and make sure you are calling the correct attribute or function from the pandas module.
For example, if you are trying to convert a pandas DataFrame column to integer, you should use the `astype()` function instead of the `int` attribute. Here is an example:
```
import pandas as pd
# create a DataFrame
df = pd.DataFrame({'A': ['1', '2', '3']})
# convert column 'A' to integer
df['A'] = df['A'].astype(int)
```
In this example, we are using the `astype()` function to convert the column 'A' to integer, instead of using the `int` attribute.
module pandas has no attribute dataframe
这个错误提示是因为你可能在代码中调用了pandas模块中不存在的dataframe属性。一般来说,pandas的DataFrame属性拼写是大写的"DataFrame",而不是小写的"dataframe"。请检查代码拼写正确并重新运行程序。
