This is the code I am using to replace text in powerpoint. First I am extracting text from powerpoint and then storing the translated and original sentences as dictionary.
prs = Presentation('/content/drive/MyDrive/presentation1.pptx')
# To get shapes in your slides
slides =
shapes = []
for slide in slides:
for shape in slide.shapes:
shapes.append(shape)
def replace_text(self, replacements: dict, shapes: List):
"""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(str(match), str(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)
I get a error

May I know why am I getting this error. What chnages should be done to resolve it. Also can I save the replaced text using prs.save('output.pptx')
New Error

>Solution :
The error you are getting ‘NameError: name ‘List’ is not defined’ occurs because ‘List’ isn’t a valid type within python Typing. Since Python 3.9, you’ll want to use ‘list[type]’
For instance:
def replace_text(self, replacements: dict, shapes: list[str]):
Alternatively, you can use python’s typing. However, this is deprecated in newer versions.
from typing import List
def replace_text(self, replacements: dict, shapes: List[str]):
