1 - 输入输出及字符串拼接

输出

name = 'fty'
print(name)

>>> fty

格式化输出

name = 'fty'
print("my name is:%s" % name)

>>> my name is:fty

输出两个参数

name = 'fty'
age = '23'
print('my name is %s and age is %s' % (name, age))

>>> my name is fty and age is 23

多个参数时将多个参数放入小括号中，逗号隔开

字符串拼接

1 通过加号拼接

first_naem = 'f'
last_name = 'ty'
name = first_name + last_name

>>> fty

2 通过格式化字符串

first_name = 'f'
last_name = 'ty'
name = "===%s===" % (first_name + last_name)

>>> ===fty===
