1. ' ASCII ' codec can ' t encode characters in position 6-7: Ordinal not in range (128)The cause of this problem is essentially ASCII encoding, in which Python naturally calls the ASCII codec to process the character stream, and throws an exception

Writing this program, I have been learning python for nearly 100 hours, on CSDN see someone ask for help using Python how to write a program of vending drinks, I think, try to write a practical sales program. Of course, just realize the basic

Find a formula The code is as follows: A=1b=2C=3Print c* (A/b) The running result is always 0, and after repeated checks are taken apart, it is found that in Python, integers can only be derived from integers. That is, the result of a except B
