I tried the code below with overflow Gunther janice carol susan richard i want the values to be copied in column c in the following condition, if col_b has value, then col_c should have the same value as col_b (regardless of col_a has value or not)
If col_b is blank, then col_c should have the same value as col_a An email with the same content is also sent from a different email address (sales@example.com) to janice doe and bcc'd to jordan doe Hopefully you can see that specifying the recipients of an email is very flexible and you can send to many people at the same time.

When on is a join expression, it will result in duplicate columns We can use.drop(df.a) to drop duplicate columns Cond = [df.a == other.a, df.b == other.bb, df.c == other.ccc] # result will have duplicate column a result = df.join(other. In the given code, the 2 is logged after 3 and 4 because the while loop blocks the main thread, delaying the execution of asynchronous code like promises and timeouts Once the loop completes, these asynchronous tasks execute in the order they were queued, with 2 being logged last Since useeffect ( () => console.log (2), [state]) registers an effect to log 2 when the state variable.
React uses shallow comparison of state and props to determine if the component must rerender When using const arr = anchors, and then setting state to arr, its the same reference to that array, thus it wont rerender Using the spread operator, const arr = [.anchors], causes arr to have a different reference to anchors Then, when setting state to that array.
