如果你的库返回一个字符串，你可以使用正则表达式来找到你想要的输出：

import re

text = "Name: Python , Color: Blue"
span = re.match("Name:.*,", text).span()
# Add 5 to starting position to remove "Name:"
print(text[span[0]+5:span[1]])

使用PyMuPDF包尝试此操作。

import fitz  # PyMuPDF
doc=fitz.open("test.pdf")
page = doc[0]

blocks = page.get_text("blocks")  # extract text separated by paragraphs

# a block is a tuple starting with 4 floats followed by lines in paragraph
for b in blocks:
    lines = b[4].splitlines()  # lines in the paragraph
    for line in lines:  # look for lines having 'Name:' and 'Color:'
        p1 = line.find("Name:")
        if p1 < 0:
            continue
        p2 = line.fine("Color:", p1)
        if p2 < 0:
            continue
        text = line[p1+5:p2]  # all text in between
        p3 = text.find(",")  # find any comma
        if p3 >= 0:  # there, shorten text accordingly
            text = text[:p3]
        # finished
