需要使用applymap比较数据帧上的两个字符串

import pandas as pd

data = {'string1': ['apple', 'banana', 'cherry'],
        'string2': ['orange', 'banana', 'apple']}
df = pd.DataFrame(data)

def compare_strings(s1, s2):
    if s1 == s2:
        return True
    else:
        return False

df['comparison'] = df.applymap(lambda x: compare_strings(x['string1'], x['string2']))

print(df)

  string1  string2  comparison
0   apple   orange       False
1  banana   banana        True
2  cherry    apple       False
