使用print出各型的 字符串
整数
浮点数
出度及精度控制
strHello = 'Hello Python'
print strHello
#出果：Hello Python
#直接出字符串1.格式化出整数
strHello = "the length of (%s) is %d" %('Hello World',len('Hello World'))
print strHello
#出果：the length of (Hello World) is 11
#print也支持参数格式化，与C言的printf似，2.格式化出16制整数
nHex = 0x20
#%x --- hex
#%d --- dec
#%d --- oct
print "nHex = %x,nDec = %d,nOct = %o" %(nHex,nHex,nHex)
#出果：nHex = 20,nDec = 32,nOct = 40
#使用整数的各个制打印同一个数3.格式化出浮点数(float)
import math
#default
print "PI = %f" % math.pi
#width = 10,precise = 3,align = left
print "PI = %10.3f" % math.pi
#width = 10,precise = 3,align = rigth
print "PI = %-10.3f" % math.pi
#前面填充字符
print "PI = %06d" % int(math.pi) #出果
#PI = 3.141593
#PI = 3.142
#PI = 3.142
#PI = 000003
#浮点数的格式化，精度、度和4.格式化出字符串(string)
#precise = 3
print "%.3s " % ("jcodeer")
#precise = 4
print "%.*s" % (4,"jcodeer")
#width = 10,precise = 3
print "%10.3s" % ("jcodeer")
#出果：
#jco
#jcod
# jco
#同于字符串也存在精度、度和。5.出列表(list)
l = [1,2,3,4,'jcodeer']
print l
#出果：[1, 2, 3, 4, 'jcodeer']
#于list直接打印即可
'''6.出字典(dictionary)'''
d = {1:'A',2:'B',3:'C',4:'D'}
print d
#出果：{1: 'A', 2: 'B', 3: 'C', 4: 'D'}
#同python也是支持dictionary出的
