从 Pandas 中的 DataFrame 中仅获取大写单词
为了只获取大写单词，我们使用正则表达式。该重模块用在这里和进口。让我们导入所有库-
import re import pandas as pd
创建一个数据帧-
data = [['computer', 'mobile phone', 'ELECTRONICS', 'electronics'],['KEYBOARD', 'charger', 'SMARTTV', 'camera']] dataFrame = pd.DataFrame(data)
现在，提取大写单词-
for i in range(dataFrame.shape[1]):
for ele in dataFrame[i]:
if bool(re.match(r'\w*[A-Z]\w*', str(ele))):
print(ele)示例
以下是代码-
import re
import pandas as pd
# create a dataframe
data = [['computer', 'mobile phone', 'ELECTRONICS', 'electronics'],['KEYBOARD', 'charger', 'SMARTTV', 'camera']]
dataFrame = pd.DataFrame(data)
# dataframe
print"Dataframe...\n",dataFrame
print"\nDisplaying only capital words...\n"
# extracting capital words
for i in range(dataFrame.shape[1]):
for ele in dataFrame[i]:
if bool(re.match(r'\w*[A-Z]\w*', str(ele))):
print(ele)输出结果这将产生以下输出-
