接下来,对两组数据进行比较,计算它们的差异水平。 # 数据比较diff=data1.symmetric_difference(data2)diff_percentage=len(diff)/len(data1|data2)*100print(f"数据差异水平为:{diff_percentage}%") 1. 2. 3. 4. 步骤3:结果分析 最后,将比较的结果可视化,以便更直观地展示数据的差异水平。 # 结果可视化imp...

The simplest way to compare two strings is with a measurement of edit distance. For example, the following two strings are quite similar: NEW YORK METS NEW YORK MEATS Looks like a harmless misspelling. Can we quantify it? Using python’s difflib, that’s pretty easy ...
