Annotating plot bar from values of other a specific column

[celinafregoso99]

I am trying to create a bar plot with matplotlib in which x values are in one column and the percentages of these values are in a separate column.


Gender Gain/Loss Final corrected classification Values percent
0 F G Benign 5619 11.658886
1 F G Likely Benign 7288 15.121901
2 F G Likely Pathogenic 324 0.672269

To carry out out my plot I have been working with the code I show below but I am not able to annotate the values of the percentage column next to the bars

# Figure Size
fig, ax = plt.subplots(figsize =(16, 9))


# Horizontal Bar Plot
ax.barh(s['Final corrected classification'], s['Values'])

# Remove axes splines
for s in ['top', 'bottom', 'left', 'right']:
    ax.spines[s].set_visible(False)
    
# Remove x, y Ticks
ax.xaxis.set_ticks_position('none')
ax.yaxis.set_ticks_position('none')

# Add padding between axes and labels
ax.xaxis.set_tick_params(pad = 5)
ax.yaxis.set_tick_params(pad = 10)

# Add x, y gridlines
ax.grid(b = True, color ='grey',
        linestyle ='-.', linewidth = 0.5,
        alpha = 0.2)
 
# Show top values 
ax.invert_yaxis()

# Add annotation to bars

for p in ax.patches:
        percentage = s["percent"].astype(int)
        x = p.get_x() + p.get_width() + 0.02
        y = p.get_y() + p.get_height()/2
        ax.annotate(percentage, (x, y))
    
# Add Plot Title
ax.set_title('Number of variants',
             loc ='left', )
 
# Add Text watermark
fig.text(0.9, 0.15, 'STP', fontsize = 12,
         color ='grey', ha ='right', va ='bottom',
         alpha = 0.7)
 
# Show Plot
plt.show()

I have been getting different error, so far I got this

Error:
