按条件划分Pandas DF单元格并保存特定字

import pandas as pd

data = {'Name': ['Alice', 'Bob', 'Charlie', 'David'],
        'Age': [25, 30, 35, 40],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}
df = pd.DataFrame(data)

# 定义一个函数，用于判断单元格中是否包含特定字
def contains_specific_word(cell_value, specific_word):
    if specific_word in str(cell_value):
        return True
    else:
        return False

# 按条件划分单元格并保存特定字
specific_word = 'New'
df['Contains Specific Word'] = df['City'].apply(lambda x: contains_specific_word(x, specific_word))

print(df)

      Name  Age      City  Contains Specific Word
0    Alice   25  New York                   True
1      Bob   30    London                  False
2  Charlie   35     Paris                  False
3    David   40     Tokyo                  False
