List search in pandas text column

I have a dataset with two columns: date and text. The text column contains unstructured information. I have a list of city names to search for in a text column.
I need to get two sets of data:
list_city = [New York, Los Angeles, Chicago]
When all records from the list with a text message match with the dataframe lines
Sample example:
df_1
data text
06-02-2022 New York, Los Angeles, Chicago, Phoenix
05-02-2022 New York, Houston, Phoenix
04-02-2022 San Antonio, San Diego, Jacksonville
Need result df_1_res:
df_1_res
data text
06-02-2022 New York, Los Angeles, Chicago, Phoenix
I tried this design, it works, but it doesn't look very nice:
df_1_res= df_1.loc[df_1["text"].str.contains(list_city[0]) & df_1["text"].str.contains(list_city[1]) & df_1["text"].str.contains(list_city[2])]
When at least one value from the list matches the text in the dataframe lines
Sample example:
df_2
data text
06-02-2022 New York, Los Angeles, Chicago, Phoenix
05-02-2022 New York, Houston, Phoenix
04-02-2022 San Antonio, San Diego, Jacksonville
Need result df_2_res:
df_2_res
data text
06-02-2022 New York, Los Angeles, Chicago, Phoenix
05-02-2022 New York, Houston, Phoenix
I tried this design, it works, but it doesn't look very nice:
df_2_res= df_2.loc[df_1["text"].str.contains(list_city[0]) | df_2["text"].str.contains(list_city[1]) | df_2["text"].str.contains(list_city[2])]
How can it be improved? Since it is planned to change the number of cities in the filtering list.

here is one way to do it
For case # 1 : AND Condition
# use re.IGNORECASE to make findall case insensitive
import re
(df_1.loc[df_1['text'].str
.findall(r'|'.join(list_city), re.IGNORECASE)
.apply(lambda x: len(x)).eq(len(list_city))])
data text
0 06-02-2022 New York, Los Angeles, Chicago, Phoenix
CASE #2 : OR Condition
#create an OR condition using join
# filter using loc
df_2.loc[df_1['text'].str.contains(r'|'.join(list_city))]
data text
0 06-02-2022 New York, Los Angeles, Chicago, Phoenix
1 05-02-2022 New York, Houston, Phoenix

Try using the isin() function
Output:

Solution with pandas.Series.str.count
list_city = ['New York', 'Los Angeles', 'Chicago']
print('\nfirst task - ALL')
df1 = df[df['text'].str.count(r'|'.join(list_city)).eq(len(list_city))]
print(df1)
print('\nsecond task - ANY')
df1 = df[df['text'].str.count(r'|'.join(list_city)).gt(0)]
print(df1)
first task - ALL
data text
0 06-02-2022 New York, Los Angeles, Chicago, Phoenix
second task - ANY
data text
0 06-02-2022 New York, Los Angeles, Chicago, Phoenix
1 05-02-2022 New York, Houston, Phoenix

Beautiful soup scraping with selenium

I'm learning how to scrape using Beautiful soup with selenium and I found a website that has multiple tables and found table tags (first time dealing with them). I'm learning how to try to scrape those texts from each table and append each element to respected list. First im trying to scrape the first table, and the rest I want to do on my own. But I cannot access the tag for some reason.
I also incorporated selenium to access the sites, because when I copy the link to the site onto another tab, the list of tables disappears, for some reason.
My code so far:
import requests
from bs4 import BeautifulSoup
import pandas as pd
import re
from selenium import webdriver
from selenium.webdriver.support.ui import Select
PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
targetSite = "https://www.sdvisualarts.net/sdvan_new/events.php"
driver.get(targetSite)
select_event = Select(driver.find_element_by_name('subs'))
select_event.select_by_value('All')
select_loc = Select(driver.find_element_by_name('loc'))
select_loc.select_by_value("All")
driver.find_element_by_name("submit").click()
targetSite = "https://www.sdvisualarts.net/sdvan_new/viewevents.php"
event_title = []
name = []
address = []
city = []
state = []
zipCode = []
location = []
webSite = []
fee = []
event_dates = []
opening_dates = []
description = []
try:
page = requests.get(targetSite )
soup = BeautifulSoup(page.text, 'html.parser')
items = soup.find_all('table', {"class":"popdetail"})
for i in items:
event_title.append(item.find('b', {'class': "text"})).text.strip()
name.append(item.find('td', {'class': "text"})).text.strip()
address.append(item.find('td', {'class': "text"})).text.strip()
city.append(item.find('td', {'class': "text"})).text.strip()
state.append(item.find('td', {'class': "text"})).text.strip()
zipCode.append(item.find('td', {'class': "text"})).text.strip()
Can someone let me know if I am doing this correctly, This is my first time dealing with site's urls elements disappear when copied onto a new tab and/or window
So far, I am unable to append any information to each list.

One issue is with the for loop.
you have for i in items:, but then you are calling item instead of i.
And secondly, if you are using selenium to render the page, then you should probably use selenium to get the html. They also have some embedded tables within tables, so it's not as straight forward as iterating through the <table> tags. What I ended up doing was having pandas read in the tables (returns a list of dataframes), then iterating through those as there is a pattern of how the dataframes are constructed.
import pandas as pd
from selenium import webdriver
from selenium.webdriver.support.ui import Select
PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
targetSite = "https://www.sdvisualarts.net/sdvan_new/events.php"
driver.get(targetSite)
select_event = Select(driver.find_element_by_name('subs'))
select_event.select_by_value('All')
select_loc = Select(driver.find_element_by_name('loc'))
select_loc.select_by_value("All")
driver.find_element_by_name("submit").click()
targetSite = "https://www.sdvisualarts.net/sdvan_new/viewevents.php"
event_title = []
name = []
address = []
city = []
state = []
zipCode = []
location = []
webSite = []
fee = []
event_dates = []
opening_dates = []
description = []
dfs = pd.read_html(driver.page_source)
driver.close
for idx, table in enumerate(dfs):
if table.iloc[0,0] == 'Event Title':
event_title.append(table.iloc[-1,0])
tempA = dfs[idx+1]
tempA.index = tempA[0]
tempB = dfs[idx+4]
tempB.index = tempB[0]
tempC = dfs[idx+5]
tempC.index = tempC[0]
name.append(tempA.loc['Name',1])
address.append(tempA.loc['Address',1])
city.append(tempA.loc['City',1])
state.append(tempA.loc['State',1])
zipCode.append(tempA.loc['Zip',1])

Filling out empty cells with lists of values

I have a data frame that looks like below:
City State Country
Chicago IL United States
Boston
San Diego CA United States
Los Angeles CA United States
San Francisco
Sacramento
Vancouver BC Canada
Toronto
And I have 3 lists of values that are ready to fill in the None cells:
city = ['Boston', 'San Francisco', 'Sacramento', 'Toronto']
state = ['MA', 'CA', 'CA', 'ON']
country = ['United States', 'United States', 'United States', 'Canada']
The order of the elements in these list are correspondent to each other. Thus, the first items across all 3 lists match each other, and so forth. How can I fill out the empty cells and produce a result like below?
City State Country
Chicago IL United States
Boston MA United States
San Diego CA United States
Los Angeles CA United States
San Francisco CA United States
Sacramento CA United States
Vancouver BC Canada
Toronto ON Canada
My code gives me an error and I'm stuck.
if df.loc[df['City'] == 'Boston']:
'State' = 'MA'
Any solution is welcome. Thank you.

Create two mappings, one for <city : state>, and another for <city : country>.
city_map = dict(zip(city, state))
country_map = dict(zip(city, country))
Next, set City as the index -
df = df.set_index('City')
And, finally use map/replace to transform keys to values as appropriate -
df['State'] = df['City'].map(city_map)
df['Country'] = df['City'].map(country_map)
As an extra final step, you may call df.reset_index() at the end.

Python3 Pandas Dataframe Split Columns

I have a column on my dataframe that contains the following
Wal-Mart Stores, Inc., Clinton, IA 52732
Benton Packing, LLC, Clearfield, UT 84016
North Coast Iron Corp, Seattle, WA 98109
Messer Construction Co. Inc., Amarillo, TX 79109
Ocean Spray Cranberries, Inc., Henderson, NV 89011
W R Derrick & Co. Lexington, SC 29072
I am having problem to capture it using regex so far my regex works for first 2 lines:
[A-Z][A-za-z-\s]+,\s{1}(Inc.|LLC)
How do I split the column to 4 additional columns? i.e. Column1 = Company Name, Column 2 = City, Column 3 = State, Column 4 = Zipcode.
Example of the output is shown below:
Company_Name City State ZipCode
Wal-Mart Stores, Inc. Clinton IA 52732

The names are probably the trickiest part, but if you know that the structure of city, state, zip will always be the same (i.e. no extra commas) you could use rsplit to split the strings. Similarly pandas has a str.rsplit method as well.
df
Address
0 Wal-Mart Stores, Inc., Clinton, IA 52732
1 Benton Packing, LLC, Clearfield, UT 84016
2 North Coast Iron Corp, Seattle, WA 98109
3 Messer Construction Co. Inc., Amarillo, TX 79109
df['Zip'] = df.Address.map(lambda x: x.rsplit(' ', 1)[-1])
df['Name'], df['City'], df['State']= zip(*df.Address.map(lambda x: x.rsplit(' ', 1)[0].rsplit(',', 2)))
df
Address Zip \
0 Wal-Mart Stores, Inc., Clinton, IA 5273 5273
1 Benton Packing, LLC, Clearfield, UT 84016 84016
2 North Coast Iron Corp, Seattle, WA 98109 98109
3 Messer Construction Co. Inc., Amarillo, TX 79109 79109
Name City State
0 Wal-Mart Stores, Inc. Clinton IA
1 Benton Packing, LLC Clearfield UT
2 North Coast Iron Corp Seattle WA
3 Messer Construction Co. Inc. Amarillo TX

Split a column and append to existing values in other columns using pandas

I am facing some hard challenge in data cleaning using pandas. I need to work on the ZIP, State and City columns in the dataframe (as attached).
This is the glimpse of the data:
City State ZIP
0 PEARLAND TX 77584
1 HOT SPRINGS AR 7191
2 PALMDALE CA 93551
3 JONESBOROY AR 72401
4 WATSONVILLE CA 95076
5 SACRAMENTO UCA 95823
6 AGOURAT HILLS CA 91301
7 JSAN DIEGO CA 92114
8 NEW PORT RICHEY FL 34655
9 BURBANK CA 91501
Challenge I am facing:
The Zip column should contain only the Zip number, The state column should have only 2 digit state code, and city should have valid city name.
For example:
City State ZIP
6 AGOURAT HILLS CA 91301
7 JSAN DIEGO CA 92114
8 NEW PORT RICHEY FL 34655
should be -
City State ZIP
6 AGOURAT HILLS CA 91301
7 JSAN DIEGO CA 92114
8 NEW PORT RICHEY FL 34655
So can anyone help me how can I achieve this using Pandas dataframe?

The best option would be to read the data once again using regex. If not, redo.
df['combined'] = df.apply(' '.join, axis = 1)
df[['City', 'State', 'Zip']] = df['combined'].str.extract('([A-Z ]+)\s+([A-Z]{2})\s+(\d+)', expand = True)
df.drop('combined', axis = 1, inplace = True)
City State ZIP
0 PEARLAND TX 77584
1 HOT SPRINGS AR 7191
2 PALMDALE CA 93551
3 JONESBOROY AR 72401
4 WATSONVILLE CA 95076
5 NaN NaN NaN
6 AGOURAT HILLS CA 91301
7 JSAN DIEGO CA 92114
8 NEW PORT RICHEY FL 34655
9 BURBANK CA 91501
