  • python中文注释问题 枯木

    在RHEL6下使用Vim写python脚本发现不能使用中文注释,后来发现是编码问题

    [wu@server python]$ cat ex4.py 
    #!/usr/bin/python
    
    #中文注释
    #cars_num
    cars = 100
    #space_car_num
    space_in_a_car = 40
    drivers = 30
    passengers = 90
    cars_not_driven = cars - drivers
    cars_driven = drivers
    carpool_capacity = cars_driven * space_in_a_car
    average_passengers_per_car = passengers / cars_driven
    
    print "There are", cars, "cars available."
    print "There are only", drivers, "drivers available."
    print "There will be", cars_not_driven, "empty cars today."
    print "We can transport", carpool_capacity, "people today."
    print "We have", passengers, "to carpool today."
    print "We need to put about", average_passengers_per_car, "in each car."
    [wu@server python]$ ./ex4.py
      File "./ex4.py", line 3
    SyntaxError: Non-ASCII character '\xe4' in file ./ex4.py on line 3, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
    

    加上# -*- coding:utf-8 -*-之后就能成功使用中文注释了

    [wu@server python]$ cat ex4.py 
    #!/usr/bin/python
    # -*- coding:utf-8 -*-
    
    #中文注释
    #cars_num
    cars = 100
    #space_car_num
    space_in_a_car = 40
    drivers = 30
    passengers = 90
    cars_not_driven = cars - drivers
    cars_driven = drivers
    carpool_capacity = cars_driven * space_in_a_car
    average_passengers_per_car = passengers / cars_driven
    
    print "There are", cars, "cars available."
    print "There are only", drivers, "drivers available."
    print "There will be", cars_not_driven, "empty cars today."
    print "We can transport", carpool_capacity, "people today."
    print "We have", passengers, "to carpool today."
    print "We need to put about", average_passengers_per_car, "in each car."
    [wu@server python]$ ./ex4.py 
    There are 100 cars available.
    There are only 30 drivers available.
    There will be 70 empty cars today.
    We can transport 1200 people today.
    We have 90 to carpool today.
    We need to put about 3 in each car.
    [wu@server python]$
