我想替换icashier.alipay.com列中的子字符串df
url
icashier.alipay.com/catalog/2758186/detail.aspx
icashier.alipay.com/catalog/2758186/detail.aspx
icashier.alipay.com/catalog/2758186/detail.aspx
vk.com
到aliexpress.com.
欲望输出
aliexpress.com/catalog/2758186/detail.aspx
aliexpress.com/catalog/2758186/detail.aspx
aliexpress.com/catalog/2758186/detail.aspx
vk.com
我尝试df['url'].replace('icashier.alipay.com', 'aliexpress.com', 'inplace=True')但它回来了empty dataframe.
