Python学习笔记一：简单的交互程序

1 name = input("Name: ")    #Python3.X中的input取代了Python2.X中的input_raw
2 age = int(input("Age: ))       #此处若不加int语句，输入时计算机会识别为字符串，为了确保计算机识别为数字，用户也可以输入数字意外的字符。int = integer意为整数
3 job = input("Job: ")
4 salary = input("Salary: ")

1 info = """
2 ----Info of %s----    #%为格式化字符串，s = string, d = digit
3 Name: %s
4 Age: %d
5 Job: %s
6 Salary: %s
7 """ % (name, name, age, job, salary)
8 print(info)

info2 = """
----Info of {_name}----
Name: {_name}
Age: {_age}
Job: {_job}
Salary: {_salary}
""".format(_name = name,
           _age = age,
           _job = job,
           _salary = salary)
print(info2)
