Hello I am working on improving my python skills in Jupyter Notebook and I am having a frustrating issue. In a larger piece of code, my input statements are being executed before the print statements although the print statement is first in the code block. Is there a way to fix this in Jupyter Notebook? I am doing a tutorial course and want to continue using this IDE. Please see attached image.

What does %% capture do in Jupyter? Capturing Output With %%capture IPython has a cell magic, %%capture , which captures the stdout/stderr of a cell. With this magic you can discard these streams or store them in a variable. By default, %%capture discards these streams.
To run a piece of code, click on the cell to select it, then press SHIFT+ENTER or press the play button in the toolbar above. Additionally, the Cell dropdown menu has several options to run cells, including running one cell at a time or to run all cells at once.
Jupyter Notebooks have a range of widgets to make these kinds of changes more user-friendly, aesthetically pleasing, and intuitive. In addition to all these benefits, you will also learn UI concepts and test code that handles user input.
Debug code in Jupyter notebooksSet the breakpoints in the selected cell and press Alt + Shift + Enter for Windows or ⌥⇧↩ for macOS. Alternatively, you can right-click the cell and select Debug Cell from the context menu.
It looks like a race condition between two streams. One possible, unsastifying solution is to wait a bit before executing input:
import time
print("Welcome")
time.sleep(0.05)
input("yes")

When I flush the print statement to force it to display, it works for me:
print("Welcome", flush = True)
input("yes")
