python- string concatenation of three methods
1. Use number plus sign (+) for splicing
String concatenation direct sum can be relatively easy to understand, but we must remember, by adding variables directly, not a variable must be quoted, or be wrong, the other numbers are to be converted to a string to be able to be summed and this is important to remember that the numbers can not be added up.
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)
The output results are as follows
---info ofwendy--- name:wendy age:26 job:it salary:8000
2. Use splicing%
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)
When the digital type, format conversion remember
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)
Output
name:llll age:89 <class 'int'> job:89 salary:1000 ---info of llll--- name: llll age: 89 job: 89 salary: 1000
3 format using the format
（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)
Output Format
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)
Output
name:liyang age:67 job:teacher salary:5000 ---info of liyang--- name:liyang age:67 job:teacher salary:5000
