AND Boolean operator syntax error - jsb83 - May-31-2019 Hello I am very new to python, any help is much appreciated. I am having problems with line 48 the AND logical operator keeps throwing up an "invalid syntax" error. I have been trying for hours to rectify this but cannot find a solution. Can some one please help. Code shown on right and on line 48 elif current_health >50 and <70: """Made by My Adventure game""" #Import import random #Variables greeting = ("welcome to my adventure game.") health = 200 difficulty = 1 #Calculations monster_hit =int(random.randint(0,100)*difficulty) monster_hit2 = int(random.randint(0,100)*difficulty) current_health = health - (monster_hit + monster_hit2) username = input("Enter your first name: ") print() print("-------------------------") print() print("Hello " + username.title() + ", " + greeting) #use , (Comma)to concatenate int variable and stings only. .title() capitalises the firt letter. print() print("Your starting health is " + str(health) + " points") # convert int to str when no calculations are not being performed on the integer number print() print("You have been hit by a monster for " + str(monster_hit + monster_hit2) + " points") print() print("After being hit, your health has dropped down to " + str(current_health)+ " points.") print() if current_health <=0: print("You have been killed by the monster, game over!") elif current_health>50 and <70: print("Be careful your health is getting close to a dangerous point, it is " + str(current_health) +" Score value point") else: print("You are on the verge of dying, be careful, your health score is" + str(current_health)+ "score value point") print(monster_hit, monster_hit2) print() RE: AND Boolean operator syntax error - buran - May-31-2019 make line 48 elif 50 < current_health < 70:if you must use and elif current_health > 50 and current_health < 70:but the first one is better RE: AND Boolean operator syntax error - jsb83 - May-31-2019 Thank you so much. Working fine now. All the best. RE: AND Boolean operator syntax error - perfringo - May-31-2019 If you are using Pythor 3.6 or later you may consider taking advantage of f-strings which makes constructing strings more natural (and subjectively more beautiful). No commas or pluses and fragmented strings, just placeholders in one string: >>> health = 200 >>> greeting = 'welcome to my adventure game.' >>> username = 'bob' >>> print(f"Hello {username.title()}, {greeting}") Hello Bob, welcome to my adventure game. >>> print(f"Your starting health is {health}") Your starting health is 200 |
