Tensorflow Introduction problem in initializing parameters

Hi,
In Tensorflow introduction assignment of course2 week 3, I am initializing my parameters in the initialize_parameters() function
b1
but its showing me invalid syntax like this
invalid
I am not able to understand why this is wrong.

Hi @Parn_Barve ,

This usually indicates there is a mismatch of parenthesis from the previous line of code. Please check.

Yes there was a problem with parenthesis. Thank you for help. Its working now.
