String class strip interface¶

What interface is this?¶

The strip method interface removes whitespaces or specified character(s) from a string’s beginning and end edges.

Basic usage¶

The strip method accepts the optional string argument.

If you skip this argument, this interface removes whitespaces (and line breaks) from a string’s beginning and end edges.

import apysc as ap

ap.Stage(
    stage_width=0,
    stage_height=0,
    background_color=ap.Color("#333"),
    stage_elem_id="stage",
)

string: ap.String = ap.String("  \n  aabbaa  ")
string = string.strip()
ap.assert_equal(string, "aabbaa")

ap.save_overall_html(dest_dir_path="string_strip_basic_usage_1/")

Also, if you specify any value to the string argument, this interface removes its character(s) from a string’s beginning and end edges.

import apysc as ap

ap.Stage(
    stage_width=0,
    stage_height=0,
    background_color=ap.Color("#333"),
    stage_elem_id="stage",
)

string: ap.String = ap.String("aabbccaa")
string = string.strip(string="a")
ap.assert_equal(string, "bbcc")

ap.save_overall_html(dest_dir_path="string_strip_basic_usage_2/")
