When the if-else condition is used inside the loop, the interpreter checks the if condition in each iteration, and the correct block gets executed depending on the result. if condition: block of statements else: block of statements Example: Print all even and odd numbers In this program, fo...

In Python, “for-loop” is widely used to iterate over a sequence, list, or any object. For loop avoids multiple usages of code lines to make the program concise and simple. The “One line for loop” is also the form of “for loop” which means that a complete syntax of “for loop...
In Python, we use a for loop to iterate over sequences such as lists, strings, dictionaries, etc. For example, languages = ['Swift', 'Python', 'Go'] # access elements of the list one by one for lang in languages: print(lang) Run Code Output Swift Python Go In the above example...
print(x) else: print("Finally finished!") Try it Yourself » Nested Loops A nested loop is a loop inside a loop. The "inner loop" will be executed one time for each iteration of the "outer loop": Example Print each adjective for every fruit: ...
As you can see, the components that you saw in the above section return in this small example of a for loop in Python: the for keyword, the variable number, the in keyword, the range() function and the code that you want to execute multiple times, print("Thank you"). That isn't ...
While Loop Inside For Loop in r中的While循环 这里有两个与while一起使用的解决方案。第一个“flag”设置为TRUE,索引设置为1,根据条件将“flag”设置为FALSE flag <- TRUEi <- 1while(flag) { print(a[[i]]) i <- i + 1 if(a[[i]] == 2) { flag <- FALSE } }#[1] 1 或者我们加一个...
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...
Python nested list loop We can have nested lists inside another list. loop_nested.py #!/usr/bin/python nums = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] for i in nums: for e in i: print(e, end=' ') print() We have a two-dimensional list of integers. We loop over the ...
awk '{ for(i=1; i<=NF; i++) print $i }' file.txt 在上述示例中,awk读取名为file.txt的输入文件,并对每一行应用操作。for循环变量i从1开始,逐渐增加,直到达到当前行的字段数(NF)。在每次循环中,使用print语句输出当前字段的值。 这样,对于输入文件中的每一行,awk会将每个字段单独输出一行。这种方式...
