如何告诉熊猫read_table一列有数值

Question

This question must have been asked before or is moot. However I can't find the answer. Pandas read_table by default takes all the data (cells) as strings. How to tell it a given column (or all of them) have numerical values?

pandas.read_table() has a dtype= param, where you can pass a dict of {column_name: dtype_you_want_for_column}
