Fix your indentation and add a colon after each if-statement<\/code> as the following and change user_input == input(':')<\/code> to user_input = input(':')<\/code>:<\/p>\n

while True:\n    print (\"Options\")\n    print (\"Write 'Quit' if you want to exit\")\n    print (\"Write '+'if you want to make an addition\")\n    print (\"Write '-' if you want to make a sottration\")\n    print (\"Write '*' if you want to make a moltiplication\")\n    print (\"Write \"https:\/\/stackoverflow.com\/\" if you wantto make a division\")\n    user_input = input(\":\") # fix this line\n    if user_input == (\"+\"):\n        num1 = float(input(\"Enter a number...\"))\n        num2 = float(input(\"Enter the second number...\"))\n        result = str(num1+num2)\n        print(\"The result is\"+ result)\n    elif user_input == (\"-\"):\n        num1 = float(input(\"Enter a number...\"))  \n        num2 = float(input(\"Enter the second number...\"))\n        result = str(num1-num2)\n        print(\"The result is\"+ result)\n    elif user_input == (\"*\"):\n        num1 = float(input(\"Enter a number...\"))\n        num2 = float(input(\"Enter the second number...\"))\n        result = str(num1*num2)\n        print(\"The result is\"+ result)\n    elif user_input == (\"https:\/\/stackoverflow.com\/\"):\n        num1 = float(input(\"Enter a number...\"))\n        num2 = float(input(\"Enter the second number...\"))\n        result = str(num1\/num2)\n        print (\"The result is\"+ result)\n<\/code><\/pre>\n
EDIT:<\/strong><\/p>\n
Below is a better version of your code that fixes few errors, like reading string input, avoid dividing by zero exception and removing float()<\/code> type casting because in python 2.7 input()<\/code> already does that for you.<\/p>\n
while True:\n    print(\"Options\")\n    print(\"Write 'Quit' if you want to exit\")\n    print(\"Write '+'if you want to make an addition\")\n    print(\"Write '-' if you want to make a sottration\")\n    print(\"Write '*' if you want to make a moltiplication\")\n    print(\"Write \"https:\/\/stackoverflow.com\/\" if you wantto make a division\")\n    user_input = raw_input(\":\")\n    if user_input == '+':\n        num1 = input(\"Enter a number...\")\n        num2 = input(\"Enter the second number...\")\n        print('The result is {}'.format(num1+num2))\n    elif user_input == '-':\n        num1 = input(\"Enter a number...\")\n        num2 = input(\"Enter the second number...\")\n        print('The result is {}'.format(num1-num2))\n    elif user_input == '*':\n        num1 = input(\"Enter a number...\")\n        num2 = input(\"Enter the second number...\")\n        print('The result is {}'.format(num1*num2))\n    elif user_input == \"https:\/\/stackoverflow.com\/\":\n        num1 = input(\"Enter a number...\")\n        num2 = input(\"Enter the second number...\")\n        if num2 == 0:\n            print(\"Can't divide by zero.\")\n        else:\n            print(\"The result is {}\".format(num1\/num2))\n<\/code><\/pre>\n
Also as suggested by other users here is an improved version:<\/p>\n
while True:\n    print(\"Options\")\n    print(\"Write 'Quit' if you want to exit\")\n    print(\"Write '+'if you want to make an addition\")\n    print(\"Write '-' if you want to make a sottration\")\n    print(\"Write '*' if you want to make a moltiplication\")\n    print(\"Write \"https:\/\/stackoverflow.com\/\" if you wantto make a division\")\n    user_input = raw_input(\":\") \n    num1 = input(\"Enter a number...\")\n    num2 = input(\"Enter the second number...\")\n\n    if user_input == \"+\":\n        result = str(num1+num2)\n    elif user_input == \"-\":\n        result = str(num1-num2)\n    elif user_input == \"*\":\n        result = str(num1*num2)\n    elif user_input == \"https:\/\/stackoverflow.com\/\":\n        if num2 == 0:\n            result = \"Can't divide by zero\"\n        else:\n            result = str(num1\/num2)\n\n    print(\"The result is\", result)\n<\/code><\/pre>\n<\/p><\/div>\n
