Given a dataset I was asked to perform 5 machine learning models on the dataset.

Here is my code:

standard_scaler = StandardScaler()
try:
  X_train=standard_scaler.fit_transform(X_train)
  X_test=standard_scaler.fit_transform(X_test)

except ValueError:

I keep getting

except ValueError:
                 ^
IndentationError: expected an indented block 

Can someone please help me figure out this issue?

>Solution :

You need a block in ValueError:

standard_scaler = StandardScaler()
try:
  X_train=standard_scaler.fit_transform(X_train)
  X_test=standard_scaler.fit_transform(X_test)
except ValueError:
    pass  #or any other value you need
