python2.7的字符串拼接

方法一：直接字符串拼接

# -*- coding: UTF-8 -*-
# 开发人:李柏霖
# 开发时间:2021/7/21 10:32
name = raw_input("Name:")
age = raw_input("Age:")
job = raw_input("job:")
salary = raw_input("salary:")
info = ''' "------info of ''' + name + '''------" Name:''' + name + ''' Age:''' + age + ''' job:''' + job + ''' salary:''' + salary + ''' '''

输出结果：

方法二：使用占位符

# -*- coding: UTF-8 -*-
# 开发人:李柏霖
# 开发时间:2021/7/21 10:32
name = raw_input("Name:")
age = raw_input("Age:")
job = raw_input("job:")
salary = raw_input("salary:")
info3=''' ——————————————————————————————占位符 %s—————————————————————————————— Name:%s Age:%s Job:%s Salary:%s '''%(name,name,age,job,salary)
print info3

输出结果：

字符串类型转换

# -*- coding: UTF-8 -*-
# 开发人:李柏霖
# 开发时间:2021/7/21 10:32
name = raw_input("Name:")
age = raw_input("Age:")
job = raw_input("job:")
salary = raw_input("salary:")
info3=''' ——————————————————————————————占位符 %s—————————————————————————————— Name:%s Age:%d Job:%s Salary:%s '''%(name,name,age,job,salary)
print info4

报错：

TypeError: %d format: a number is required, not str

原因分析：

输入的都是字符串类型，我们转换一下格式就可以了。

合拼为一句：

age = int(raw_input("Age:"))

占位符拼接

方法一：

# -*- coding: UTF-8 -*-
# 开发人:李柏霖
# 开发时间:2021/7/21 10:32
name = raw_input("Name:")
age = int(raw_input("Age:"))
job = raw_input("job:")
salary = raw_input("salary:")
info5=''' ——————————————————————————————占位符 {name5}—————————————————————————————— Name:{name5} Age:{age5} Job:{job5} Salary:{salary5} '''.format(name5=name,age5=age,job5=job,salary5=salary)

效果一样：

方法二：

name = raw_input("Name:")
age = int(raw_input("Age:"))
job = raw_input("job:")
salary = raw_input("salary:")
info6=''' ——————————————————————————————占位符 {0}—————————————————————————————— Name:{0} Age:{1} Job:{2} Salary:{3} '''.format(name,age,job,salary)
print info6
