Python merge variables and text into new variable

so I have the line:

text="Temp :" + TempVar + "C CPUTemp: " + CPUTempVar + "C"

How would I get that to work as a string on text?

I endorse @Cyber's answer (the format method) as the straightforward, modern Python way to format strings.

For completeness, however, the old way (common prior to Python 2.6) was a string interpolation operator:

text = 'Temp : %dC CPUTemp: %dC' % (TempVar,CPUTempVar)

It still works in the latest Python 3 releases, and will commonly be seen in older code.

Or you could use my say package to do inline string substitution (or printing) similar to what you'd expect from Ruby, Perl, PHP, etc.:

from say import *

text = fmt('Temp : {TempVar}C CPUTemp: {CPUTempVar}C')

You need to cast as strings if you want to concat non strings to strings:

TempVar = 100
CPUTempVar = 100
text="Temp: " + str(TempVar) + "C CPUTemp: " + str(CPUTempVar) + "C"

print(text)
Temp: 100C CPUTemp: 100C

You can use format to create a string from your variables.

TempVar = 100
CPUTempVar = 50
text = 'Temp : {}C CPUTemp: {}C'.format(TempVar,CPUTempVar)

>>> text
'Temp : 100C CPUTemp: 50C'
