python字符串格式化的三种方式

今天突然想了解一下字符串的格式化的方法,总结了一下:

第一种:是用%s 和%d来格式化字符串

 

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

"""
info = '''

===============info of %s==============
name: %s
age: %d
salary: %d
job: %s
''' % (name,name,age,salary,job)

print(info)

 

第二种:

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:

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)
