In this article, I will explain what an ifelse statement is and provide code examples. In the form shown above: is an expression evaluated in a Boolean context, as discussed in the section on Logical Operators in the Operators and Expressions in Python tutorial. (You will see why very soon.) is a valid Python statement, which must be indented. (You will see why very soon.) For Example: The followings are conditional statements. A loop in C consists of two parts, a body of a loop and a control statement. When the condition evaluates to False, the loop stops and the program continues beyond the loop.
