Help: how to fix problem with SyntaxError: 'return' outside function

Language Help Python

How to fix this? This is my code:

# function for calculating kinetic energy
def cal_kinetic_energy(m, v):
# kinetic energy formula
    KE = 0.5 * m * v**2
return KE

# main function
def main():
# input mass from user
    m = input("Please enter the mass (kg): ")
# input velocity from user
	v = input("Please enter the velocity (m/s): ")

# call kinetic energy method
print( cal_kinetic_energy(m, v), "is the calculated kinetic energy")

# call main
main()

but

Syntax errors detected :

Line 5:
return KE
^
SyntaxError: ‘return’ outside function

What is the problem? The syntax tells you exactly what the problem is, and even at which line.

You may either indent that offending line so that it’s aligned with KE = 0.5 * m * v**2

def cal_kinetic_energy(m, v):
# kinetic energy formula
    KE = 0.5 * m * v**2
    return KE

Alternatively, simply return the computed value

def cal_kinetic_energy(m, v):
# kinetic energy formula
    return 0.5 * m * v**2
