💡 Hint

Common Mistakes

Using '+' or '||' which are not valid chain operators.

Using '|>' which is not the LangChain pipe operator.

The pipe operator for chaining in LangChain is |, which connects the output of chain1 to the input of chain2.

💡 Hint

Common Mistakes

Mixing different operators between chains.

Using '+' which concatenates but does not chain.

Use the | operator repeatedly to chain multiple LangChain chains in sequence.

💡 Hint

Common Mistakes

Using '+' which concatenates but does not chain.

Using '||' which is not a valid operator here.

The correct operator to chain LangChain chains is |. Using '+' or other operators will cause errors or unexpected behavior.

4fill in blank

hard

Fill both blanks to chain two chains and then call the combined chain.

LangChain

combined = chain1 [1] chain2
output = combined.[2](input_data)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'execute' or 'call' which are not LangChain chain methods.

Using '+' instead of the pipe operator.

Use | to chain the chains, then call invoke method to execute the combined chain with input data.

5fill in blank

hard

Fill all three blanks to chain three chains, run the combined chain, and print the output.

LangChain

combined_chain = chainA [1] chainB [1] chainC
result = combined_chain.[2](input_text)
print([3])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'execute' instead of 'invoke'.

Printing the wrong variable name.

Using '+' instead of the pipe operator.

Chain the chains with |, run the combined chain with invoke, and print the variable result holding the output.
