DataFrame.info()

verbose : {None, True, False}, optional

Whether to print the full summary. None follows the display.max_info_columns setting. True or False overrides the display.max_info_columns setting.

buf : writable buffer, defaults to sys.stdout

max_cols : int, default None

Determines whether full summary or short summary is printed. None follows the display.max_info_columns setting.

memory_usage : boolean/string, default None

Specifies whether total memory usage of the DataFrame elements (including index) should be displayed. None follows the display.memory_usage setting. True or False overrides the display.memory_usage setting. A value of ?deep? is equivalent of True, with deep introspection. Memory usage is shown in human-readable units (base-2 representation).

null_counts : boolean, default None

Whether to show the non-null counts

• If None, then only show if the frame is smaller than max_info_rows and max_info_columns.
• If True, always show counts.
• If False, never show counts.
