AttributeError: 'str' object has no attribute 'isoformat'. Did you mean: 'format'?

This error occurs when you try to use the isoformat method on a string object, but it is not defined on strings. The isoformat method is defined on datetime objects, and it returns the string representation of the datetime object in the ISO format.

If you meant to format a string, you can use the format method instead. For example:

my_str = "Hello, {}!"
formatted_str = my_str.format("world")

If you meant to work with a datetime object, make sure you are creating or passing a datetime object to the isoformat method. For example:

import datetime

my_datetime = datetime.datetime.now()
isoformat_str = my_datetime.isoformat()

这个错误是由于您在代码中使用了错误的方法名。正确的方法名是'format'而不是'forrmat'。您可以将错误的方法名更正为'format'来解决这个错误。

AttributeError: 'str' object has no attribute 'colunm'. Did you mean: 'count'?

这个错误是因为你在字符串对象上调用了一个不存在的属性'colunm'。正确的拼写应该是'column'。你可能想要使用'count'属性来计算字符串中某个字符出现的次数。下面是一个示例代码来演示如何使用'count'属性：

str1 = "Hello, world!"
count = str1.count('o')
print(count)  # 输出：2
