1、python的環(huán)境搭建

2、給出下載鏈接地址

3、if和while混合使用
age=56
count = 0

while count<3:
guess_age=int(input("請(qǐng)輸入年齡："))

if guess_age == age:
print("yes,you got it")
break
elif guess_age > age:
print("pls it it smaller")
else:
print("pls make it bigger")
count +=1
if count >= 3:
confrimex = input("do you want to try again..?")
if confrimex != 'n':
count = 0

4、for使用
for i in range (2,100,3):
print("loop %d",i)

5、用戶的交互
id=int(input("id:"))
print(type(id))
name = input("name:")
age = input("age:")
sallary=input("sallary:")

msg='''
#拼接字符串---------------------index of '''+name+'''
id:'''+str(id)+'''
name:'''+name+'''
age:'''+str(age)+'''
salary:'''+sallary

print(msg)
print("--------------------------------------------------------------")

msg='''
#格式化輸出-----------------------index of----------------%s
id=%d
name=%s
age=%s
salary=%s
''' % (name,id,name,age,sallary)
print(msg)
print("--------------------------------------------------------------")
msg='''
#變量占位符-----------------------index of----------------{_name}
id={_id}
name={_name}
age={_age}
salary={_salary}
'''.format(_name=name,_id=id,_age=age,_salary=sallary)
print(msg)
print("--------------------------------------------------------------")
msg='''
#數(shù)字占位符-----------------------index of----------------{0}
id={1}
name={0}
age={2}
salary={3}
'''.format(name,id,age,sallary)
print(msg)
