在pdf转为文本的时候,经常会多出空格,影响数据观感,因此需要去掉文本中多余的空格,而文本中的英文之间的正常空格需要保留,输入输出如下:
input:我今天 赚了 10 个亿,老百姓very happy。
output:我今天赚了10个亿,老百姓very happy。
代码
def clean_space(text): """" 处理多余的空格 """ match_regex = re.compile(u'[/u4e00-/u9fa5。/.,,::《》、/(/)()]{1} +(?<![a-zA-Z])|/d+ +| +/d+|[a-z A-Z]+') should_replace_list = match_regex.findall(text) order_replace_list = sorted(should_replace_list,key=lambda i:len(i),reverse=True) for i in order_replace_list: if i == u' ': continue new_i = i.strip() text = text.replace(i,new_i) return text
re.sub(" +", " ", s)
import re s = " info has been found (+/- 100 pages, and 4.5 mb of .pdf files) now i have to wait untill our team leader has processed it and learns html. "re.sub(" +", " ", s)
