如何将Python程序中新学生判断的欢迎输出移至程序末尾

修改思路 #

• 先把对应欢迎信息存入变量，不立即打印
• 完成所有输入操作后，再输出存储好的欢迎信息
• 修正原代码语法错误：print**(...) 应为 print(...)，移除最后一行多余的反引号

修改后的代码 #

sStudent = input("Are you a new student? y/n")
# 将欢迎信息暂存到变量中
if "y" == sStudent:
    welcome_msg = "Welcome to Henry Ford College!"
elif "n" == sStudent:
    welcome_msg = "Welcome back to HFC!"

iCreditRate = input("Enter credit hour rate")
iNumCred = int(input("Enter number of credits this semester"))
sLabFee = input("Do you have any Lab fees?")

# 所有输入完成后，最后打印欢迎信息
print(welcome_msg)

可选优化（处理非y/n输入） #

如果要避免用户输入非y/n时变量未定义报错，可添加默认分支：

sStudent = input("Are you a new student? y/n")
if "y" == sStudent:
    welcome_msg = "Welcome to Henry Ford College!"
elif "n" == sStudent:
    welcome_msg = "Welcome back to HFC!"
else:
    welcome_msg = "Hello! Welcome to Henry Ford College!"

iCreditRate = input("Enter credit hour rate")
iNumCred = int(input("Enter number of credits this semester"))
sLabFee = input("Do you have any Lab fees?")

print(welcome_msg)
