what expression should i wrtie in python for this R code

x=["245.2","256.3"]
y=["205.7","205.1"]
z=["202.4","250.5"]
'''output <-- function(x=NULL, y=NULL , z= NULL)
{
if(is.vector(x) & is.vector(y) & is.vector(z)){
    data %>%
      select(x,y,z) %>% #selecting the desired columns
      filter_at(.vars= x, any_var(.==1)) %>%
      filter_at(.vars= y, any_var(.==1)) %>%
      filter_at(.vars= z, any_var(.==1)) %>%
      summarise(Total= n())      
  } else if(is.vector(x) &is.vector(y)){
      data%>%
      select(x,y)
      filter_at(.vars = x, any_vars(.==1))%>%
      filter_at(.vars = y, any_vars(.==1)) %>%
      summarise(Total= n())      
    } else if(is.vector(x)){
      data%>%
      select(x)
      filter_at(.vars = x, any_vars(.==1))%>%
      summarise(Total= n())
    } else
        print("enter a valid vector of code")
}
'''

here i have to put a function of filter and is to check that data is vector than function is pass. thanks in advance
