测试代码-单元测试没看出来哪里不对

变色幽灵

直接上图：写了个测试类，怎么也没看出来提示中的'Santiago,Chile - population 50000' != 'Santiage,Chile - population 50000'
是哪里不一样了～？

再附上city_functions类：
#encoding:utf-8
def city_functions(city,country,population = ''):
        if population:
                return city.title() + "," + country.title() + " - " + "population " + str(population)
        else:
                return city.title() + "," + country.title()
