根据字母'l‘或'L’在另一列的字符串中创建新列

import pandas as pd

# 创建一个包含字符串的DataFrame
data = {'Strings': ['Hello', 'World', 'Cloud', 'Computing']}
df = pd.DataFrame(data)

# 创建新列并初始化为空
df['Contains L'] = ''

# 遍历每个字符串
for index, row in df.iterrows():
    string = row['Strings']
    
    # 检查字符串是否包含字母'l'或'L'
    if 'l' in string or 'L' in string:
        df.at[index, 'Contains L'] = 'Yes'
    else:
        df.at[index, 'Contains L'] = 'No'

# 打印结果
print(df)

      Strings Contains L
0      Hello        Yes
1      World        Yes
2      Cloud         No
3  Computing         No
