python code is unreachable
# In computer programming, unreachable code is part of the source code of a
# program which can never be executed because there exists no control flow path
# to the code from the rest of the program.
# Unreachable code is sometimes also called dead code, although dead code may
# also refer to code that is executed but has no effect on the output of a
# program.
# Example (Python 3):
def check_x():
x = int(input("Give me a number: "))
if x < 10:
return False
return True
print(x)
# Here, the code print(x) is unreacheable because there is always a return
# statement before, so x will never be printed.
