如何將if ifif語句的輸出保存到python數據幀中的新變量？

Question

如何編輯以下腳本以將輸出保存為原始數據框中的新變量？

AKA：將輸出保存為每個if ifif語句的新變量，而不是print函數？

import re

df = pd.read_excel('edmundstest.xlsx')

for Keyword, Landing_Page in zip(df["Keyword"], df["Landing_Page"]):

# the url
    if "/2019/" in Landing_Page:
        new_model_core_incentives = Landing_Page
        print(f"new_model_core_incentives {new_model_core_incentives}")
    elif re.search("/(?:(?:20)|(?:19))\d{2}/", Landing_Page):
        used_model_core_incentives = Landing_Page 
        print(f"used_model_core_incentives {used_model_core_incentives}")    

# the "keywords"
    if "2019" in Keyword:
        new_word = Keyword
        print(f"new_word {new_word}")
    elif re.search("/(?:(?:20)|(?:19))\d{2}/", Keyword) is None:
        old_word = Keyword
        print(f"old_word {old_word}")

即： new_model_core_incentives或used_model_core_incentives作為數據幀中的新變量， new_word和old_word作為數據幀中的新變量？

你可以使用字典：

dict[Keyword]=f"new_model_core_incentives {new_model_core_incentives}"
dict2[Keyword]=f"old_word {old_word}"

像這樣的東西：

import re

df = pd.read_excel('edmundstest.xlsx')

dict, dict2 = {}, {}

for Keyword, Landing_Page in zip(df["Keyword"], df["Landing_Page"]):

# the url
    if "/2019/" in Landing_Page:
        new_model_core_incentives = Landing_Page
        print(f"new_model_core_incentives {new_model_core_incentives}")
    elif re.search("/(?:(?:20)|(?:19))\d{2}/", Landing_Page):
        used_model_core_incentives = Landing_Page 
        dict[Keyword]=f"new_model_core_incentives {new_model_core_incentives}"    

# the "keywords"
    if "2019" in Keyword:
        new_word = Keyword
        print(f"new_word {new_word}")
    elif re.search("/(?:(?:20)|(?:19))\d{2}/", Keyword) is None:
        old_word = Keyword
        dict2[Keyword]=f"old_word {old_word}"
