What is the use of colon in python after loop and condition?
it starts a new code block. all the indented code after the colon will be considered as one block. for example, in loops it means that all the indented code after the colon will be run on each iteration. example: for i in range(4): # this code will run 4 times # this code will be ran once.
Why should you never put a semicolon at the end of the while loop's parentheses?
There are rare occasions where you would do that, but in general you don't want to do that for most while loops because the semi-colon is a statement by itself (it becomes part of the loop). For example, while (a > b) ; would terminate the loop body, whereas: while (a > b) b++ ; would have the increment of 'b' as part of the loop. In the first example it might cause an infinite loop, depending on whether or not a is greater than b. The semi-colon character means the semantic end of a statement. Putting it with the while logically doesn't make much sense most of the time. Note: Never say never, for example the following is completely legal: while ((*to++ = *from++)!='\0');
What is the difference between a for loop and a while loop in java?
ComparisonThe conditions for both the 'while' and 'for' loop are exactly the same, but in each flow structure the conditions are placed in different locations. A 'for' loop places the full condition within the 'for' loop whereas the 'while' loop places the counter variable outside of the loop.The 'for' loop is used when the length of the loop is known whereas the 'while' loop is usually used when the length of the loop is unknown.'for' loop exampleWithin the parentheses the complete condition is contained. The condition has 3 parts delimited by a colon ';'. The first part sets the counter 'int i' to 0, the second part tells the loop to stop when the counter is 5. The third part tells java to increment the counter by 1 value each time the loop iterates.for ( int i = 0; i < 5; i++)'while' loop exampleWith the 'while' loop the counter is initialized outside of the 'while' loop. Inside the parentheses of the loop the condition is set to stop looping when the counter reaches a value of 5. Inside of the 'while' loop block the counter is set to increment by 1 value each time the loop iterates.int i = 0;while ( i < 5 ) {i++}
Definition and comments for loop?
The C and C++ for loop is defined as...for (init-expression; test-expression; loop-expression) loop-statement;The init-expression is executed once.At the top of the loop, test-expression is evaluated. If it is false, control passes to the statement following loop-statement.The loop-statement is executed. It may be one statement, it may be a block of statements, or it may be no statement. If it is no statement, the semi-colon is required.At the bottom of the loop, loop-expression is executed, and then control passes to the test-expression at the top of the loop for another go-around.Each of init-expression, test-expression, and loop-expression may be missing. The semi-colons are required. The formal "forever" loop is for (;;) loop-statement; in which case the only way out is the break statement.Since each of init-expression, test-expression, and loop-expression can have side-effects, sometimes a loop is constructed with no loop-statement, and all processing is done between the parentheses.If test-expression is initially false, loop-expression and loop-statement are never executed. The init-expression is always executed only one time, and test-expression is executed at least one time.At any point during loop-statement, the breakstatement will exit to the statement following loop-statement, and the continue statement will jump to the loop-expression at the bottom of the loop.
Can there be multiplle increment exression in increment part of the for loop statement?
Yes, you can have multiple expressions in the increment poart of the for loop statement. Just use the comma, and each expression will be evaluated from left to right.
What is the portion of the colon on the left side in the digestive system?
Decending Colon
What abdominal quadrant best describes the location of the sigmoid colon?
The sigmoid colon is located in the lower left quadrant of the abdomen.
Which organs lie in the left upper quadrent?
The left upper quadrant of the abdomen contains the pancreas, the spleen, the left kidney, the left adrenal gland, the left-most aspect of the liver, and the splenic flexure of the colon along with the left-most transverse colon and the superior aspect of the descending colon.
What organs are on the lower left side of your body?
i think the colon?----------------------------------------------------------------------------------------------------------Organs on the left side of the body include (as the previous poster answered) the colon, the stomach, the spleen and left kidney. Also parts of the small intestines will be in the left part.As to the question of which organs are on the lower leftside of the body specifically, the descending colon and sigmoid colon (both are parts of the colon) would be the correct answer.
The colon travels upward from the cecum to the under surface of the liver?
The ascending colon extends from the cecum to the under surface of the liver where it turns to the left to become the transverse colon.
