python中For循环

打印出1到100的数，不包含100
for i in range(1,100):
if i==23:
print "great,you got your luncky number:",i
print 'The unmber is:',i
================23会被重复打印===============================


for i in range(1,100):
    if i==23:
         print "great,you got your luncky number:",i
    else:
         print "The unmber is:",i
================23只会打印一次===============================


for i in range(1,100):
        if i==23:
                print "great,%s lucky number:"%i#%s，引用外部的变量；外部的变量则为：引号之外的变量
        print "The number is:",i
