Slide of ppt. If you could see the first word "Custom" is not replaced even though it is present in the dictionary translation

我想知道为什么某些单词会出现这种情况。

换词代码

prs = Presentation('/content/drive/MyDrive/presentation2.pptx')


# To get shapes in your slides

slides = [slide for slide in prs.slides]
shapes = []
for slide in slides:
    for shape in slide.shapes:
        shapes.append(shape)


def replace_text(replacements: dict, shapes: List[str]):
    """Takes dict of {match: replacement, ... } and replaces all matches.
    Currently not implemented for charts or graphics.
    """
    for shape in shapes:
        for match, replacement in replacements.items():
            if shape.has_text_frame:
                if (shape.text.find(match)) != -1:
                    text_frame = shape.text_frame
                    for paragraph in text_frame.paragraphs:
                        for run in paragraph.runs:
                            cur_text = run.text
                            new_text = cur_text.replace(match, replacement)
                            run.text = new_text

            if shape.has_table:
                for row in shape.table.rows:
                    for cell in row.cells:
                        if match in cell.text:
                            new_text = cell.text.replace(match, replacement)
                            cell.text = new_text

replace_text(translation, shapes) 

prs.save('output5.pptx')

run.text 输出

Custom Entity Extraction - Custom इकाई निष्कर्षण

【问题讨论】：

先打印每个run.text，看看你会得到什么
问题可能不在于代码的 powerpoint 部分。了解如何创建minimal reproducible example 并编辑问题。
replace 只替换第一个匹配项。
@PeterWood 我已经发布了 run.text 的结果
@PeterWood 不正确。 replace 默认替换所有。只有第一个 n 匹配有一个可选参数。
