How to have a percentage chance of executing a command
I have 10 things that I want to print if selected. However, each of them should have a different percentage chance.
I've tried the following:
chance = (random.randint(1,100))
if chance < 20:
print ("20% chance of getting this")
The problem is that if I do another one, say chance <25, if randint is 10, wouldn't both odds <25 and probability <20 work at the same time?
Here is the code that I want to get after this happened.
print ("You selected Grand Theft Auto")
gta = input ("To commit GTA input GTA")
if gta in ("gta", "Gta", "GTA"):
EDIT:
Ok so I tried this but it keeps giving 3 outputs.
print ("You selected Grand Thief Auto")
gta = input ("To commit GTA type GTA")
if gta in ("gta", "Gta", "GTA"):
chance = random.randint(0,100)
if chance <= 1:
print ("You stole a Bugatti Veryron")
chance = random.randint(0,100)
if chance <= 5:
print ("You stole a Ferrari Spider")
chance = random.randint(0,100)
if chance <= 10:
print ("You stole a Audi Q7")
chance = random.randint(0,100)
if chance <= 15:
print ("You stole a BMW X6")
chance = random.randint(0,100)
if chance <= 20:
print ("You stole a Jaguar X Type")
chance = random.randint(0,100)
if chance <= 25:
print ("You stole a Ford Mondeo")
chance = random.randint(0,100)
if chance <= 30:
print ("You stole a Audi A3")
chance = random.randint(0,100)
if chance <= 35:
print ("You stole a Ford Fiesta")
chance = random.randint(0,100)
if chance <= 40:
print ("You stole a Skoda Octavia")
chance = random.randint(0,100)
if chance <= 45:
print ("You got caught!")

You code is correct. To solve this, you first need to add =
inside your first if-statement
one as such:
if chance <= 20
The next thing to do is add a return statement at the end of your footprint, as such:
if (chance <= 20):
print(#Stuff)
return
This status return
will terminate the execution of any program and return to another task or simply be executed.
Finally, the last thing to do is add all the other increments as such:
if (chance <= 20):
print(#Stuff)
return
if (chance <= 25):
print(#Stuff)
return
...
if (chance <= #last_number):
print(#Stuff)
return
It would be prudent to be sure that you stumble upon everything as stated in the odds you are looking for as well.
Good luck.

ok, so if you want two mutually exclusive events, with one being 20% of the time and the other 25% of the time, then
chance = random.randint(1,100)
if chance <= 20:
print "20% chance of getting this"
elif chance <= 20+25:
print "25% change of getting this"
if you want them to be independent and not influence each other, you need to create another random number.
chance = random.randint(1,100)
if chance <= 20:
print "20% chance of getting this"
chance = random.randint(1,100)
if chance <= 25:
print "25% change of getting this"
