当使用pandas处理数据时，有时需要重命名DataFrame的列名。这可以通过 rename函数来实现。下面是关于 rename函数的使用方法。rename函数的基本语法如下：DataFrame.rename(columns=None, inplace=False)参数说明：columns：用于指定新的列名的字典（字典的键为原始列名，值为新的列名），或者一个可调用对象（如函数、lambda...
然后确定哪些列以Unnamed开头,屏蔽它们,并使用cumcount来确定要添加到末尾的数字(在可能有多个连续的Unnamed:columns的情况下),然后使用ffill来获取前一个不以“Unnamed”开头的列标签。指定具有此序列的列。 Sample Data import pandas as pd import numpy as np df = pd.DataFrame(columns=['Reconnaissance', '...
