python打印带下标的字母组合

使用Python给论文画图时，想让python在图中打印λn，此处的n是下标。

def convert_text(text, is_superscript=True):
    normal_chars = "0123456789"
    superscript_chars = "⁰¹²³⁴⁵⁶⁷⁸⁹"
    subscript_chars = "₀₁₂₃₄₅₆₇₈₉"

    if is_superscript:
        mapping = str.maketrans(normal_chars, superscript_chars)
    else:
        mapping = str.maketrans(normal_chars, subscript_chars)
    converted_text = text.translate(mapping)
    return converted_text


input_texts = ['λ1','λ2','λ3','λ4']
for input_text in input_texts:
    superscript_text = convert_text(input_text, is_superscript=True)
    subscript_text = convert_text(input_text, is_superscript=False)
    print("Input Text: ", input_text)
    print("Superscript Text:", superscript_text)
    print("Subscript Text:", subscript_text)
