如何在python中将不同的字符串附加到特定长度。示例：
enter Chunks_of_rows = []
for line in text_blocks: # text_blocks is a json file
lines = line['lines']
for chunk in lines:
bbox = chunk['bbox']
for k,v in row_chunk.items():# k is the bbox and v is the number of times k appears.
# So I want to append the k to a list and split the list to another list.
# ie. if k appears ten times it should appends move to a new line after it appends the last object
# print(k,v)
if k == bbox[1]:
span = chunk['spans']
# print(span)
for text in span:
text = text['text']
Chunks_of_rows.append(text)
#Here is the bbox
