在pandas read_csv中将百分比字符串转换为浮点数Pandas 可以在字符串列上使用 Python 的字符串处理功能。
usage_mb = usage_b / 1024 ** 2 # convert bytes to megabytes return "{:03.2f} MB".format(usage_mb) gl_int = gl.select_dtypes(include=['int']) converted_int = gl_int.apply(pd.to_numeric,downcast='unsigned') print(mem_usage(gl_int)) ...
因此可以写一个转换函数： def convert_currency(value): """ 转换字符串数字为float类型 ...
用法:pandas.to_numeric(arg, errors=’raise’, downcast=None) 返回值:如果解析成功,则为数字。请注意,返回类型取决于输入。如果是 Series,则为 Series,否则为 ndarray。 范例1:在此示例中,我们将“通货膨胀率”列的每个值转换为浮点数。 码: Python3 ...
