Python in shiny app

[siddharthsusheel]

Hi team,

I am new to Rstudio and Shiny. I am in need of running python code when we click a button in UI I created in shiny app. Is it possible to do this?
Attaching the code of UI.
library(shiny)

ui <- fluidPage(
titlePanel("R Session Cleaner"),
label = "Choose",
radioButtons("radio", label = h3("Radio buttons"),
choices = list("Test1" = 1, "Test2" = 2,
"Test3" = 3),
selected = 1),

hr(),
fluidRow(column(3, verbatimTextOutput("value")))

)
server <- function(input, output) {
output$value <- renderPrint({ input$radio })
}
shinyApp(ui, server)
Thanks in advance,

Best,
Siddharth

You can source python functions and use it as any other function in R by using the reticulate package, but you can't directly use python syntax on a shiny app.

@andresrcs So how can I import the python code in shiny app when I click a button? Do you guys have an example to post? Or can you edit my code and add like dumb python code and post it?

[andresrcs]

Using a command like this `reticulate::source_python("python_script.py")

But sourcing your python code each time you press a button doesn't sound like a good idea, it would be better to source your python function at session level and then use that function in your button as it was regular R code.

If you need more specific help please provide a minimal reproducible example (reprex) illustrating your issue. Have a look at this guide, to see how to create one for a shiny app

Shiny debugging and reprex guide

Shiny issues can be challenging to resolve relative to other problems with your code or statistical methods. Shiny apps are often large, complex projects with interacting files. When seeking help from others it is considered polite to: First, do your best to work through RStudio's debugging tools to diagnose your issue on your own. Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue. You can do this with a reproducible example ("reprex"). Shiny Debugging Errors in Shiny code can be difficult to track down. If you don't know where your problem is coming from, you can track it down with some o…
