Name Error

[atik666]

I am getting Name Error every time I am trying to execute a program.
My code and everything is right though.
Name Error: Name 'b' is not defined

def celsius_to_fahrenheit(temp):
 newTemp = (9/5)* temp +32
print("The Celsius temperature",temp,"is equivalent to",newTemp,end='')
print("degress Fahrenheit")

output:

def celsius_to_fahrenheit(temp):
 newTemp = (9/5)* temp +32

print("The Celsius temperature",temp,"is equivalent to",newTemp,end='')
print("degress Fahrenheit")
Traceback (most recent call last):
