Python: round(random.uniform) printing wrong float value on output console but in background its correct value

Question

See the following code

import re
import random
s = "~|21|050000|voltage|current|ApparentPower|12345~"
for _ in range(100):
    vol_val = round(random.uniform(230, 260), 2)
    vol = '{:.2f}'.format(vol_val)
    replaced = re.sub('voltage', vol, s)

    def cur(match):
        return str(round(random.uniform(10,30), 2))
    replaced1 = re.sub('current', cur, replaced)
    #print(replaced1)
    spl_vol = replaced1.split("|")[3]
    spl_cur = replaced1.split("|")[4]
    print(spl_vol,spl_cur)


    mul = float(spl_vol)*float(spl_cur)
    dc = format(mul, ".2f")
    mull = str(dc)
    #print(mull)
    txt = replaced1
    replacedapp = re.sub("ApparentPower", mull, txt)
    print(replacedapp)

In this code iam Generating two random values at each iteration, and using those random values, i am replacing the actual values at each iteration.

At each Iteration i am Replacing Three Values voltage by first voltage random value current by first current random value and I am Replacing ApparentPower by multiplication result of voltage and current.

Here my problem is, voltage and current values displaying wrong values as shown in below (when i printed those values separately, values are correct at background)

~|21|050000|231.86|19.67|4560.69|12345~ --------- printed properly

236.36 26.5 ------------in background current value is correct

~|21|050000|236.36|26263.54|6263.54|12345~ -------- but here current value displayed wrong

234.59 21.59------------ here voltage value at background correct

~|21|050000|234.59|21.59|5064.80|12345~ -------------here also printed correct

236.58 24.14-------------------here voltage value at background correct

~|21|050000|235711.048|24.14|5711.04|12345~ ------------------- but on console displayed wrong

please anyone help me

you can run my code you will get my problem
