python—字符串拼接三种方法
1.使用加号(+)号进行拼接
字符串拼接直接进行相加就可以，比较容易理解，但是一定要记得，变量直接相加，不是变量就要用引号引起来，不然会出错，另外数字是要转换为字符串才能够进行相加的，这点一定要记住，不能把数字直接相加。
name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary:")
info ='''
---info of '''+name+ '''---
name:'''+name+'''
age:'''+age+'''
job:'''+job+'''
salary:'''+salary+'''
'''
print(info)
输出结果如下
---info ofwendy--- name:wendy age:26 job:it salary:8000
2.使用%进行拼接
name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary:")
info ='''
---info of %s---
name: %s
age: %s
job: %s
salary: %s
'''%(name,name,age,job,salary)
print(info)
当有数字类型，记得转换格式
name = input("name:")
age = int(input("age:")) #integer
print(type(age))
job = input("job:")
salary = input("salary:")
info ='''
---info of %s---
name: %s
age: %d
job: %s
salary: %s
'''%(name,name,age,job,salary)
print(info)
输出结果
name:llll age:89 <class 'int'> job:89 salary:1000 ---info of llll--- name: llll age: 89 job: 89 salary: 1000
3 使用format格式
（1）
name=input("name:")
age=input("age:")
job=input("job:")
salary=input("salary:")
info2 ='''
---info of {name}---
name:{name}
age:{age}
job:{job}
salary:{salary}
'''.format(name=name,
age=age,
job=job,
salary=salary)
print(info2)
输出格式
name:qwww age:12 job:ty salary:1348 ---info of qwww--- name:qwww age:12 job:ty salary:1348
（2）
name=input("name:")
age=input("age:")
job=input("job:")
salary=input("salary:")
info2 ='''
---info of {0}---
name:{0}
age:{1}
job:{2}
salary:{3}
'''.format(name,age,job,salary)
print(info2)
输出结果
name:liyang age:67 job:teacher salary:5000 ---info of liyang--- name:liyang age:67 job:teacher salary:5000

输出格式
name:qwww age:12 job:ty salary:1348 ---info of qwww--- name:qwww age:12 job:ty salary:1348
（2）
name=input("name:")
age=input("age:")
job=input("job:")

info2 ='''
---info of {0}---
name:{0}
age:{1}
job:{2}
salary:{3}
'''.format(name,age,job,salary)
print(info2)
输出结果
name:liyang age:67 job:teacher salary:5000 ---info of liyang--- name:liyang age:67 job:teacher salary:5000
