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
