是否有一个与R的invisible（）函数等效的Python

Question

我是Python的新手，想知道Python（或IPython）是否与R中的invisible（）函数等效。invisible（）函数返回值，但如果以交互方式运行，则不显示它们，而是仅使它们可用进行分配。例如：

doStuff <- function(x) {
   // blah blah 
   return(invisible(retValue))
}

z = doStuff(x) // z has the return value
doStuff(x) // retValue doesn't get displayed

Answer 1

There does not seem to be a proper function in Python that is the same as R's invisible() function. However, you can simply use a variable set to a boolean value and then use an if statement to check if the boolean is set to True then you return the output of the function. Below is a simple version of what the code could look like, you can make this more complex and improve it (if this does not help you then I suggest that you put some research into function outputs in python):

def function(INPUTS):
  # function code to get ouput
  return_value = False
  if return_value == True:
    return ouput
