How do I fix the Type Error: a float is required?

Question

It says that a float is required. Can anyone help me fix this code:

from time import sleep
print("Welcome to this game of random.") ; sleep(1.0)
print("Type in your name:") ; sleep(0.5)
playerName = raw_input()
print("Welcome " + playerName + " Type how fast do you want the text to go in this format: 1.0") ; sleep(1.0)
speed = raw_input()
print("You choosed: " + speed) ; sleep(speed)

Is there an error that needs to be fixed?

@GamersHub, I agree with JBernardo, you should be learning Python 3. — lmiguelvargasf, Sep 25 '19 at 02:04
@JBernardo I will soon once I finish with this project of mine. — Sergio Ley, Sep 25 '19 at 02:19

speed is a string and you are doing sleep(speed)

sleep requires a float or int so you need to do a sleep(float(speed)). This assumes the input will be a number and therefore won't fail when converting to a float

You should be validating the input of speed to ensure it is a proper format using try/except

Because sleep takes a number (int or float) as parameter, you need to cast the value returned by raw_input when it is assigned to speed. I think you are using Python 2, so raw_input which equivalent in Python 3 is input, will return a string:

from time import sleep
print("Welcome to this game of random.") ; sleep(1.0)
print("Type in your name:") ; sleep(0.5)
playerName = raw_input()
print("Welcome " + playerName + " Type how fast do you want the text to go in this format: 1.0") ; sleep(1.0)
## LOOK AT THE FOLLOWING LINE
speed = float(raw_input())
print("You choosed: " + str(speed)) ; sleep(speed)

Also, do not forget to convert speed to str since you cannot concatenate a str and float.
