s = "Turned robot " + clockwise + " for " + str(time) + " seconds"
TypeError: cannot concatenate 'str' and 'int' objects
This error is occurring because you are trying to concatenate a string and an integer using the + operator. You need to convert the integer value to a string using the str() function before you can concatenate it with the string.
Here is an example of how you can fix this error:
s = "Turned robot " + clockwise + " for " + str(time) + " seconds"
Alternatively, you can use string formatting to create the string:
s = "Turned robot {} for {} seconds".format(clockwise, time)
The Result Disappear the error , proof :
