How to apply decimal and thousand separator to numbers in cbar?

Question

I want to apply decimal and thousands separator to cbar in Seaborm plot in order to see numbers formatted like this: 4.294.967.295,00 . I know how to format xaxis and yaxis , but cannot apply this formating to cbar .

plt.figure(figsize=(12,8))
ax = sns.heatmap(df, annot=False, linewidths=.5)
ax.get_yaxis().set_major_formatter(
    matplotlib.ticker.FuncFormatter(lambda x,p: str(int(x))+":00"))
plt.show()

Answer 1

This template code should help you out. Takes an unformatted number, adds the "," before the last 2 digits, then goes through and adds the "." every 3 characters.

number = "1000000000"
temp = ""
temp += number[:-2] + "," + number[-2:]
e = list(temp.split(",")[0])
for i in range(len(e))[::-3][1:]:
    e.insert(i+1,".")
result = "".join(e)+","+temp.split(",")[1]
print(result)

This is result for the static number I gave.: 10.000.000,00
