python - 编写一个简单的 Python 程序

Question

我在为初级编程类(class)编写简单的 Python 程序时遇到了问题。如果有人可以查看我目前拥有的代码并指导我朝着正确的方向前进，将不胜感激!这是代码:

帮助满足护士到患者人员配置需求的计划

def main():
    print 'Welcome to the PACU nurse to patient program'
    print
    patients = inputPatients()
    nurses = getNurses(patients)
    nurseAssistants = getAssistants(nurses)
    printInfo = (patients, nurses, nurseAssistants)
   
    raw_input()

def inputPatients():
    patients = input('Enter the number of patients for this shift (up to 40): ')
    return patients

def getNurses(patients):
    nurses = (1.0 / 3.0) * patients
    return nurses

def getAssistants(nurses):
    nurseAssistants = (1.0 / 2.0) * nurses
    return nurseAssistants

def printInfo(patients, nurses, nurseAssistants):
    print 'The number of patients for this shift is:', patients
    print 'The number of nurses needed is:', nurses
    print 'The number of nurses Assistants is:', nurseAssistants


main()

Answer 1

将最后一段代码改为:

def printInfo(patients, nurses, nurseAssistants):
    print 'The number of patients for this shift is:', patients
    print 'The number of nurses needed is:', nurses
    print 'The number of nurses Assistants is:', nurseAssistants

main()

由于 python 是基于缩进执行的。此外，从 printInfo 语句中删除 = 并使其成为:

nurses = getNurses(patients)
nurseAssistants = getAssistants(nurses)
printInfo(patients, nurses, nurseAssistants)
