使用print函数在没有'或'的情况下用Python打印一个句子

Question

下面是我的代码,我正在使用Python2.7

#list of angle couples
phipsi=[[48.6,53.4],[-124.9,156.7],[-66.2,-30.8],[-58.8,-43.1], \
[-73.9,-40.6],[-53.7,-37.5],[-80.6,-16.0],[-68.5,135.0], \
[-64.9,-23.5],[-66.9,-45.5],[-69.6,-41.0],[-62.7,-37.5], \
[-68.2,-38.3],[-61.2,-49.1],[-59.7,-41.1],[-63.2,-48.5], \
[-65.5,-38.5],[-64.1,-40.7],[-63.6,-40.8],[-66.4,-44.5], \
[-56.0,-52.5],[-55.4,-44.6],[-58.6,-44.0],[-77.5,-39.1], \
[-91.7,-11.9],[48.6,53.4]]
#minimal deviation tolerated for the 1st number
a=-57-30
#maximal deviation tolerated for the 1st number
b=-57+30
#minimal deviation tolerated for the 2nd number
c=-47-30
#maximal deviation tolerated for the 2nd number
d=-47+30
i=0
#Check if the couple fit into the intervals of numbers
while i < len(phipsi):
    if phipsi[i][0]>a and phipsi[i][0]<b:
        if phipsi[i][1]>c and phipsi[i][1]<d:
            print ('the couple ', phipsi[i] ,' has his angles in helix')
    else:
        print ('the couple ', phipsi[i] ,' does not have his angles in helix')
    i=i+1

这就是我得到的

('the couple ', [-55.4, -44.6], ' has his angles in helix')
('the couple ', [-58.6, -44.0], ' has his angles in helix')
('the couple ', [-77.5, -39.1], ' has his angles in helix')
('the couple ', [-91.7, -11.9], ' does not have his angles in helix')
('the couple ', [48.6, 53.4], ' does not have his angles in helix')

我怎样才能得到

the couple [-77.5, -39.1] has his angles in helix
the couple [-91.7, -11.9] does not have his angles in helix

我检查了帮助部分或其他符号,但无法弄清楚...谢谢你的帮助

在Python中,2.x print不是一个函数,而是一个语句,它不包括打印对象列表周围的parens.在Python中,3.x print被更改为一个函数.您正在使用Python 3.x语法.

您有两种选择:

1. 请改用Python 2.x语法,跳过parens: print a, b, c
2. 添加from __future__ import print_function以禁用print语句并改为使用print函数.这使得在最近的Python 2.x中使用Python 3.x语法.

目前你正在打印一个tuple,你正在看到repr那个元组,即你将print((a,b,c))使用Python 3.x打印功能得到什么.

注意:print自动添加空格,不需要将它们添加到字符串中.
