在Python中为高维数据命名列

When I read in a .txt file python gives automatic names that are not very useful (i.e. 0, 0.1, 0.2, 0.3...). How do I rename all my columns without having to explicitly type it all?

当我读入.txt文件时,python会给出不太有用的自动名称(即0,0.1,0.2,0.3 ......)。如何重命名我的所有列而不必显式输入所有列?

For example, how do I quickly rename the variables V1 to V200?

例如,如何快速将变量V1重命名为V200?
