接下来,我们使用mermaid语法标识一个甘特图示例,展示了使用多行代码和一行代码实现同样功能的时间对比。 2022-05-012022-05-012022-05-022022-05-022022-05-032022-05-032022-05-042022-05-042022-05-05Initialize ListInitialize ListFor Loop and IfFor Loop and
With the help offorloop, we can iterate over each item present in the sequence and executes the same set of operations for each item. Using aforloops in Python we can automate and repeat tasks in an efficient manner. So the bottom line is using the for loop we can repeat the block of...
One Line for Loop in Python Using List Comprehension with if-else Statement The “If else” with “List comprehension” creates more powerful operations like saving space or fast processing repetitive programs. We can perform multiple operations using a single line for loop conditions of list compre...
This is where a nested for loop works better. The first loop (parent loop) will go over the words one by one. The second loop (child loop) will loop over the characters of each of the words. words=["Apple","Banana","Car","Dolphin"]forwordinwords:#This loop is fetching word from...
for i in range(3): if i == 2: break print(i, end=' ') # 打印0和1 else: print("Loop completed without encountering a 'break' statement.")5.循环控制语句：range()函数：生成一个起始默认为0的序列，通常与for循环一起使用。def print_numbers(n): for i in range(1, n+1): print(i)...

# for example when reading a large file, we only care about one row at a time def csv_reader(file_name): for row in open(file_name, 'r'): yield row # generator comprehension x = (i for i in range(10)) Iterator Iterator is like range(11), compare to list = [0,1,...,10...
Example: Loop Through a String If we iterate through a string, we get individual characters of the string one by one. language = 'Python' # iterate over each character in language for x in language: print(x) Run Code Output P y t h o n Here, we have printed each character of the...
