In this section, we will see how to use if-else statements with a loop. If-else is used when conditional iteration is needed. For example, print student names who got more than 80 percent. The if-else statement checks the condition and if the condition is True it executes the block of...
在for语句中,我们不需要显式地判断遍历是否结束,因为for语句会自动根据可迭代对象的长度来判断遍历是否结束。对于字符串来说,它是一个可迭代对象,它的长度就是字符串的长度。 在上面的示例代码中,string是一个字符串。当for语句遍历完字符串中的所有字符后,会自动结束循环,不再执行下一次迭代。 3. 示例代码 下面...

python1---variable,condition,function and loop Python is like a programming language that's based on a snake. It is a weird language,is is strange,is's not easily understood by others.Welcome to being a PythonisaIt turns out that what Python was named for was Monty Python's Flying Circu...
Usingforloops withif-elseconditional statements We’ve seen how usefulforloops can be, but you don’t really unleash the power of these loops until you use them with conditional statements likeif-else. if-elsestatements help the programmer make decisions and guide the program’s flow. To refre...
For example, say that you want to implement a number-guessing game. You can do this with awhileloop: Pythonguess.py fromrandomimportrandintLOW,HIGH=1,10secret_number=randint(LOW,HIGH)clue=""# Game loopwhileTrue:guess=input(f"Guess a number between{LOW}and{HIGH}{clue}")number=int(guess...
# Use a for loop to evaluate each element in the data for num in data:# Use the ternary operator to determine if the number is even or odd result = 'even' if num % 2 == 0 else 'odd'# Optionally, print the result of the ternary operator for each element print(f'The number {...
Python provides two keywords to terminate a loop prematurely, they are Break and Continue. Break statement terminates the loopimmediately, we can introduce the break keyword with aconditional statementlikeifin our program. list= [1,2,3,4,]foriinlist:ifi ==3:breakprint(i) ...
