怎么操作

你看下我这个帖子是不是你想要的?https://www.cda.cn/discuss/post/details/605e80b13a599107cc1ea643

df.head( ) 是一个dataframe 类型对象

print(df.head( )) 就是print这个dataframe对象 ,print默认分隔符sep为空格,结尾end的默认值是换行符 \n, 所以print一个dataframe 无法和dataframe自己呈现的样式一模一样。

主要是模拟生成不同的数据，这些数据可以用来研究算法模型的原理的

这两个函数用来产生不同的数据，产生的数据主要是用来研究熟悉算法模型。

这里 首先要理解python的引用符 “=” 的用法， pyplot.subplots() 会返回两个对象，画板 fig 与 坐标轴ax。我们可以使用一个变量去接收这两个对象，也可以使用两个变量分别接收。

fig,ax= pyplot.subplots() 这个代码就是使用两个变量去分别接收两个变量。

如果函数或者表达式有返回值的时候会在交互式的开发工具内输出这个返回的对象，如果是在ipython 或者notebook中会显示[out] 标识

print()将数据以字符的形式输出到标准输出设备上，一般来说就是当前的交互开发工具内（如：python终端、ipython 终端或者 jupyter notebook）

两者还有一个区别，print 使用的是对象 的__str__方法 ，直接终端回车调用的是__repr__方法，当输出的是包含转义符的字符串时比较明显，print 会进行转义 而后者直接输出不做转义处理

经过正则表达式提取出来的英文（如下）还存在数字和标点符号，是什么原因？

完美解决，之前换成1.7.1还一直报错，多谢~

digit_list是数字列表
chinese_list是中文列表
english_string  是英文字符串
你可以看一下

老师，怎么提取返回结果其中一部分出来，例如英文？

如果把两个数字合并成一个字符串就没有什么意义了，你要不要再考虑下

就是三部分我只要其中一部分

数字和中文都不要最外面的中括号

英文改为字符串

我已经给你分成了三部分，你可以根据需要进行选择调用。如果需要更加复杂的需求就需要把需求描述的更清晰

老师，追加提问:
['227,000', '227']
['川沙公路']
Economy Gains Jobs in January Under President Trump - Breitbart,,The U. S. economy gained
返回的这三个部分：假如我只要英文（或者中文），应该怎么提取？

收到，谢谢老师！

import re
str1='Economy Gains 227,000 Jobs in January Under President Trump - Breitbart,川沙公路,The U. S. economy gained 227'
#先用正则表达式提取字符串里面的数字生成数字列表
pattern1=re.compile("\d+,?\d+")
digit_list=pattern1.findall(str1)
#再把数字从字符串里面替换为空白，然后生成新的字符串str2
str2=re.sub(pattern1,"",str1)
#再把str2里面的中问找出来生成中文列表
zhongp1=re.compile('[\u4e00-\u9fa5]+')
chinese_list=zhongp1.findall(str2)
#再把中文从字符串里面替换为空白，然后生成新的字符串english_string
english_string=re.sub(zhongp1,"",str2)
#digit_list,chinese_list,english_string就是你想要的。
for i in [digit_list,chinese_list,english_string]:
    print(i)

'Economy Gains 227,000 Jobs in January Under President Trump - Breitbart,川沙公路,The U. S. economy gained 227'

比喻这句，保留成三部分

英文：'Economy Gains Jobs in January Under President Trump Breitbart,The U. S. economy gained '

中文：川沙公路

数字：227000,227
