帮我把以下js代码转换为python代码:function f(n) { for (var r = "", t = 0; t < 4 * n.length; t++) r += "0123456789abcdef".charAt((n[t >> 2] >> ((t % 4) * 8 + 4)) & 15) + "0123456789abcdef".charAt((n[t >> 2] >> ((t % 4) * 8)) & 15); return r; }

好的,以下是将该 JavaScript 代码转换为 Python 代码的结果:
```python
def f(n):
r = ""
for t in range(4 * len(n)):
r += "0123456789abcdef"[(n[t >> 2] >> ((t % 4) * 8 + 4)) & 15]
r += "0123456789abcdef"[(n[t >> 2] >> ((t % 4) * 8)) & 15]
return r
```
请注意,Python 和 JavaScript 的语法有所不同,因此在转换代码时可能需要适当调整代码以使其符合 Python 语法规则。

(function () { var data = getSignTime(); var token = "a8a0cde0d32347b79fca1efaf2aff907"; var nonce=("0000" + (Math.random()*Math.pow(36,4) << 0).toString(36)).slice(-4); var sign = calcSign(data,token,nonce); postman.setGlobalVariable('nonce', nonce); postman.setGlobalVariable('sign', sign); postman.setGlobalVariable('signTime', data); })(); function getSignTime(){ return parseInt(new Date().getTime() / 1000); } function calcSign(data,token,nonce) { delete data['sign']; var sign = CryptoJS.SHA256(data+token+nonce+data).toString(); return sign.toUpperCase(); }能将此JS代码转换成python代码吗
当然,这段 JS 代码可以转换成 Python 代码,如下所示:
import hashlib
import random
import time
def getSignTime():
return int(time.time())
def calcSign(data, token, nonce):
del data['sign']
data_str = ''.join([key+str(value) for key,value in data.items()])
raw_str = f"{data_str}{token}{nonce}{data_str}"
sign = hashlib.sha256(raw_str.encode('utf-8')).hexdigest()
return sign.upper()
data = {"param1": "value1", "param2": "value2", "sign": "xxx"}
token = "a8a0cde0d32347b79fca1efaf2aff907"
nonce = "0000" + format(int(random.random() * pow(36, 4)), 'x')[-4:]
sign = calcSign(data, token, nonce)
print("nonce:", nonce)
print("sign:", sign)
print("signTime:", getSignTime())
将下面代码转换成python代码:
这是一个JavaScript代码,将一个字符串中的每个单词的首字母大写,其他字母小写,并返回新的字符串。
```
function capitalize(str) {
var words = str.split(' ');
for (var i = 0; i < words.length; i++) {
var letters = words[i].split('');
letters[0] = letters[0].toUpperCase();
for (var j = 1; j < letters.length; j++) {
letters[j] = letters[j].toLowerCase();
}
words[i] = letters.join('');
}
return words.join(' ');
}
```
以下是相应的Python代码:
```
def capitalize(str):
words = str.split(' ')
for i in range(len(words)):
letters = list(words[i])
letters[0] = letters[0].upper()
for j in range(1, len(letters)):
letters[j] = letters[j].lower()
words[i] = ''.join(letters)
return ' '.join(words)
```
