python日常應(yīng)用中難免會進(jìn)行一系列的數(shù)據(jù)結(jié)構(gòu)轉(zhuǎn)換或者進(jìn)制轉(zhuǎn)換，具體示例函數(shù)代碼如下

i = int('111');
print '轉(zhuǎn)換為整數(shù):' + str(i);

f = float('111');
print '轉(zhuǎn)換為浮點(diǎn)數(shù):' + str(f);

c = complex('111')
print '轉(zhuǎn)換為復(fù)數(shù):' + str(c);

r = repr('111');
print '轉(zhuǎn)換為表達(dá)式字符串:' + str(r);

print '轉(zhuǎn)換為字符串:' + str('111');

e = eval("{1: 'a', 2: 'b'}");

print 'eval表達(dá)式轉(zhuǎn)換為字符串為python對象:' + e[1];

listTuple = [1,2,3,4,5];
t = tuple(listTuple)
print 'tuple將list轉(zhuǎn)換為元組:' + str(t);

l = list(t);
print '元祖序列轉(zhuǎn)換為list:' + str(l);

o = ord('a');
print 'ord將ascii轉(zhuǎn)換為數(shù)字:' + str(o);

ch = chr(48)

print '將0-256數(shù)字轉(zhuǎn)換成對應(yīng)的ascii字符' + str(ch);

h = hex(48);
print 'hex 將十進(jìn)制轉(zhuǎn)換為十六進(jìn)制' + str(h);

oc = oct(48);
print 'hex 將十進(jìn)制轉(zhuǎn)換為八進(jìn)制' + str(oc);
