I am a complete beginner to coding and python so It is probably very simple. So my problem is that am learning how to put if and else function based on the users input and i dont know how to connect between the two.

age = input("enter your age: ")
yes = "welcome"
no = "too bad then"
ans = [yes, no]
if age == "18":print(yes)
else: input("you're not old enough, would you like to enter anyways?: {ans} ")if yes:print(yes)else:print(no)

this is the code i made based on what ive learned so far it is probably full of mistake. I wanted to connect the 'if' and 'else' function to the input("you're not old enough, would you like to enter anyways?: {ans} ") the answer would be yes or no which would print diffrent things.

Note that when using or, as soon as the first expression (in the order specified) is True, the next expressions are ignored since the result will be True regardless. The same happens when using and; as soon as a False is found, the next expressions are ignored since the result will be False

For your specific question the solution is:

if int(input("enter your age: ")) >= 18 or input("you're not old enough, would you like to enter anyways? ").lower().startswith('y'):print("welcome")  
else: print("too bad then")

for a more general-purpose task (writing an interpreter or similar) you need to use function pointers and a look-up table (usually a dictionary). Here is a working example:

import math
import timedef add(*args):"Adds numbers together"if len(args)>0:print(sum((float(arg) for arg in args)))def mult(*args):"Multiplies numbers together"if len(args)>0:print(math.prod((float(arg) for arg in args)))def nothing(*args):passdef alias(*args):"Creates a new alias for a given action"action, alias, *_ = argsif action not in LUT:print("Cannot create an alias for an undefined action!")else:aliases[alias]=actionprint(f"Successfully created alias '{alias}' for '{action}'")def print_help(*args):"Displays valid options and what they do"for keyword in LUT:doc = LUT[keyword].__doc__print(f"{keyword} : {doc if doc is not None else '?'}")print(f"To exit the program, type any one of: {', '.join(termination_keywords)}")def print_aliases(*args):groupings= {action : [] for action in LUT}for alias in aliases:groupings[aliases[alias]].append(alias)for action, aliases_ in groupings.items():if len(aliases_)>0:print(f"{action} : {', '.join(aliases_)}")# Look Up Table
LUT = {'help':print_help,'add':add,'mult':mult,'nop' : nothing,'alias' : alias,'print_aliases': print_aliases}aliases = {'+':'add','sum':'add','total': 'add','*':'mult','multiply':'mult','prod':'mult','nothing' : 'nop','pass': 'nop'
}termination_keywords = {'end','exit','quit','q'}print(f"""Enter your the desired action and its arguments as space seperated values.
For example: add 1 2 3 4 5Defined actions are:""")
print_help()
# Sometimes the input is displayed before the help is done printing, a small delay fixes the issue
time.sleep(0.5)while True:print("#"*20)action, *args = input("What do you want to do? ").split(' ')action = action.lower()if action in termination_keywords:break;if action in LUT:LUT[action](*args)elif action in aliases:LUT[aliases[action]](*args)else:print("Undefined action!")
