There’s nothing built-in, but it’s just a loop to do the replacement in-place:
for i, word in enumerate(words):
if word == 'chicken':
words[i] = 'broccoli'
or a shorter option if there’s always exactly one instance:
words[words.index('chicken')] = 'broccoli'
or a list comprehension to create a new list:
new_words = ['broccoli' if word == 'chicken' else word for word in words]
any of which can be wrapped up in a function:
def replaced(sequence, old, new):
return (new if x == old else x for x in sequence)
new_words = list(replaced(words, 'chicken', 'broccoli'))

No such method exists, but a list comprehension can be adapted to the purpose easily, no new methods on list needed:
words = 'I like chicken'.split()
replaced = ['turkey' if wd == "chicken" else wd for wd in words]
print(replaced)
Which outputs: ['I', 'like', 'turkey']
