Common Dupes
JS:
- How can I access and process nested objects, arrays, or JSON?
- How do I return the response from an asynchronous call?
- Why is my variable unaltered after I modify it inside of a function? - Asynchronous code reference
- JavaScript closure inside loops – simple practical example
Python:
- List of lists changes reflected across sublists unexpectedly
- How do I clone a list so that it doesn't change unexpectedly after assignment?
- Strange result when removing item from a list while iterating over it
- How to remove items from a list while iterating?
- Why does "a == x or y or z" always evaluate to True? How can I compare "a" to all of those?
- How to test multiple variables for equality against a single value?
- Importing installed package from script with the same name raises "AttributeError: module has no attribute" or an ImportError or NameError (file named the same as imported module)
- Does Python have a string 'contains' substring method?
- Why does code like `str = str(...)` cause a TypeError, but only the second time? (shadows builtin function, then tries to call builtin)
- How to use variables in SQL statement in Python?
- How can I access the nested data in this complex JSON, which includes another JSON document as one of the strings?
