源码：

#!/usr/bin/python
# -*- coding: UTF-8 -*-

counter = 100 # 赋值整型变量
miles = 1000.0 # 浮点型
name = "John" # 字符串

print counter
print miles

print name

eclipse报错如下：

Encountered "counter" at line 8, column 7. Was expecting one of:

原因：

python3.0版本后print需要用()

详细参考https://stackoverflow.com/questions/19878100/python-was-expecting-one-of-newline

修改如下：

#!/usr/bin/python
# -*- coding: UTF-8 -*-

counter = 100 # 赋值整型变量
miles = 1000.0 # 浮点型
name = "John" # 字符串

print (counter)
print (miles)
print (name)
