命令符中:python -m pydoc range python 交互模式中:help(range) 我们来摘抄一下: class range(object) | range(stop) -> range object | range(start, stop[, step]) -> range object | | Return an object that produces a sequence of integers from start (inclusive) | to stop (exclusive) by ...
Return an object that produces a sequence of integers from start (inclusive) to stop (exclusive) by step. range(i, j) produces i, i+1, i+2, ..., j-1. start defaults to 0, and stop is omitted! range(4) produces 0, 1, 2, 3. These are exactly the valid indices for a list ...

简洁性:使用range()可以非常简洁地生成一系列数字。 内存效率:range()返回的是一个“range对象”,它是一个惰性序列,只在需要时才生成下一个值,因此对于大范围的数字序列来说,内存占用很小。 类型 range()函数返回的是一个range类型的对象。 应用场景 循环遍历:在for循环中使用range()来遍历一定范围内的数字。
Let’s look at another example using Python for looprange: Example 2 for i in range (0, 10): print(i) The output: You can see how the above example can be used to print a list of numbers within a specified range. You can also use it to do some simple mathematics and print out...
# Basic for loop for i in range(5): print(i) # To iterate over a list names = ["Zach", "Jay", "Richard"] for name in names: print(name) # To iterate over indices and values in a list # Way 1 for i in range(len(names)): print(i, names[i]) # Way 2 for i, name ...
A range in Python is an object representing an interval of integers, often used for looping. The range() function can be used to generate sequences of numbers that can be converted to lists. for i in range(5) is a loop that iterates over the numbers from 0 to 4, inclusive. The ...
range函数 range函数在for循环语句中经常出现。它可以产生一系列的整数,来看下它的官方文档: class range(object): """ range(stop) -> range object range(start, stop[, step]) -> range object Return an object that produces a sequence of integers from start (inclusive) # 产生start到stop之间的一系...
3:Starting number (inclusive). 10:Endpoint (exclusive, not included). 2:Increment (steps by2in each iteration). print(i): Prints the current value ofiin each loop iteration. What is the Use of Range Function in Python? Python Rangefunction is a valuable tool for programmers. It allows you...
# Import the time module, which provides time-related functions like sleep() import time # Loop over a range of numbers from 1 to 5 (inclusive) for i in range(1, 6): # Print a loading message with a percentage that updates on the same line print(f"\rLoading... {i*20}%", end...
