在跨DataFrame行执行多条If语句的场景中,可以使用apply函数结合lambda表达式来实现。 apply函数可以对DataFrame的每一行或每一列应用指定的函数,lambda表达式可以用于编写简洁的匿名函数。 以下是一个示例代码,演示如何跨DataFrame行执行多条If语句: 代码语言:txt 复制 import pandas as pd # 创建示例DataFrame df = pd....
This PR adds a pre-condition to the changeset that drops the constraint where we will skip it if the constraint has already been dropped. Bugs producing false negatives in the precondition (i.e. thinking the constraint doesn't exist when it actually does) would have been caught by all exis...
