While loop falls under the category of indefinite iteration.Indefinite iteration means that the number of times the loop is executed isnt specified explicitly in advance. The only syntax that will work is the proper one line if statement which has the format: value_if_true if expression else value_if_false. Let us The if-else conditions are sufficient to implement the control flow in the Python scripts. View another examples Add Own solution Python for Data Science #4 If statements. Write the return statement with an if expression in a single line of Python code example. Heres what happens when Python reaches a line of code containing a header for a while-loop: Python checks to see whether the condition evaluates to the value True.
