Instead of looping over a list of words and converting them to upper case: newlist = [] for word in oldlist: newlist.append(word.upper()) #word.upper()中是将word字符串转化为大写字母,但并不改变word里的值 you can use map to push the loop from the interpreter into compiled C code: ...
尝试修改我们simple.for.py代码中range()调用的参数,并查看打印出什么。熟悉一下。 在序列上进行迭代 现在我们有了所有迭代序列的工具,让我们在此基础上构建示例: # simple.for.2.pysurnames = ['Rivest','Shamir','Adleman']forpositioninrange(len(surnames)):print(position, surnames[position]) 前面的代码...

In this section, you’ll learn how to do basic arithmetic, such as addition, subtraction, multiplication, and division, with numbers in Python. Along the way, you’ll learn some conventions for writing mathematical expressions in code.AdditionAddition is performed with the + operator:...
However, sometimes, you may need to get an integer quotient for numbers which are not evenly divisible. Such an operation is called integer division. Use the floor division operator // to remove the digits after the decimal point. The code snippet below demonstrates how to perform division in...
