<human>:  Give me a Python program to subplot but not able to set xticklabels.
<bot>:)
  return ax

# Enter the number of rows and columns
nrows = 2
ncols = 3

# Enter the index
index = 1

# Enter the figure size
figsize = (10, 10)

# Calling the function
ax = subplot(nrows, ncols, index, figsize)

#Remember to inspect code for bugs.
