熊猫**DataFrame.to_string()**函数将数据帧渲染成控制台友好的表格输出。语法:data frame . to _ string(buf = None,col_space=None,header=True,index=True,na_rep='NaN ',formatters=None,float_format=None,sparsify=None,index _ names = True,justify = None,max_rows=None,max_cols=None,show_...
df['float_col'] = df['float_col'].astype('int') 或者我们将其中的“string_col”这一列转换成整型数据,代码如下 df['string_col'] = df['string_col'].astype('int') 当然我们从节省内存的角度上来考虑,转换成int32或者int16类型的数据, df['string_col'] = df['string_col'].astype('int8'...
