可以使用以下代码将其读取为DataFrame: python import pandas as pd # 读取txt文件为DataFrame df = pd.read_csv('data.txt') # 显示DataFrame的内容 print(df) 运行上述代码后,将输出: text name age gender 0 Alice 30 F 1 Bob 25 M 这样,你就成功地将txt文件读取为Pandas的DataFrame对象,方便后续的...
在Python中,可以使用pandas库来处理多行文本文件并将其转换为DataFrame。下面是一个示例代码: 代码语言:txt 复制 import pandas as pd # 读取多行文本文件 with open('file.txt', 'r') as file: lines = file.readlines() # 创建DataFrame df = pd.DataFrame({'text': lines}) # 打印DataFrame print...
import pandas as pd # Extract the required data from the text file using regular expressions amounts = [int(m) for m in re.findall(r'Amount\s*:\s*(\d+)', text)] withdraw_statuses = re.findall(r'Withdraw\s+Status\s*:\s*(\w+)', text) accounts = re.findall(r'Account\s*:...

pandas 使用python和panda为从文本文件导入到 Dataframe 的数据设置密钥您可以使用pandas.DataFrame.join：
import pandas as pd from pandas import Series, DataFrame #一、读写文本格式的数据 # 1、读取文本文件 # 以逗号分隔的(CSV)文本文件 !cat examples/ex1.csv # 由于该文件以逗号分隔,所以我们可以使用read_csv将其读入一个DataFrame: df = pd.read_csv('examples/ex1.csv') ...
"""df=pd.DataFrame()# 初始化一个DataFrame对象df['电影名称']=movie_name df['电影链接']=movie_url df['电影评分']=movie_star df['评分人数']=movie_star_people df['导演']=movie_director df['主演']=movie_actor df['上映年份']=movie_year ...

data = {} for child in root: data[child.tag] = child.text 然后,我们可以使用pandas库将字典转换为DataFrame: 代码语言:txt 复制 import pandas as pd df = pd.DataFrame.from_dict(data, orient='index', columns=['Value']) 最后,我们可以打印DataFrame来查看结果: ...
