s = pd.Series({0: 'registration address-complement-insert-confirmation input',
 1: 'decision-tree first-interaction-validation options',
 2: 'decision-tree invalid-format-validation options',
 3: 'decision-tree first-interaction-validation options',
 4: 'registration address-complement-request view',
 5: 'onboarding return-start origin',
 6: 'registration address-complement-request origin',
 7: 'decision-tree identified-regex options',
 8: 'decision-tree first-interaction-validation options',
 9: 'decision-tree first-interaction-validation options'})

我有下面的序列对象。我想做的是Map它，并将“onboarding return-start origin”之后的每一个字符串都标记为true。有什么想法可以让我建立这个条件吗？
预期结果

s = pd.Series({0: False,
 1: False,
 2: False,
 3: False,
 4: False,
 5: True,
 6: True,
 7: True,
 8: True,
 9: True})
