python字符串格式化的三种方式

python字符串格式化有三种方式，首先我们来看第一种：

这一种方式是用%s 和%d来格式化字符串

 1 name = input("name:")
 2 age = int(input("age:"))
 3 salary = int(input("salary:"))
 4 job = input("job:")
 5 
 6 """
 7 info = '''
 8 
 9 ===============info of %s==============
10 name: %s
11 age: %d
12 salary: %d
13 job: %s
14 ''' % (name,name,age,salary,job)
15 
16 print(info)

第二种方式：

name = input("name:")
age = int(input("age:"))
salary = int(input("salary:"))
job = input("job:")

info2 = '''
===============info of {_name}=============
name: {_name}
age: {_age}
salary: {_salary}
job: {_job}
'''.format(_name = name,
           _age = age,
           _salary=salary,
           _job=job)

print(info2)

第三种方式：

name = input("name:")
age = int(input("age:"))
salary = int(input("salary:"))
job = input("job:")

info3 = '''
============info of {0}=================
name: {0}
age: {1}
salary: {2}
job: {3}
'''.format(name, age, salary, job)

print(info3)

掌握这三种方式，对于字符串格式化就没什么大问题了
