我對python很陌生。我正在嘗試撰寫一個程式來測驗一個數字是否在給定范圍內，然后告訴你這個數字是奇數還是偶數。我在檢測它是奇數還是偶數的部分遇到問題。看來，如果它只是重??復我的均勻陳述。這是代碼：
while True:
num = int(input("Please enter an integer between 1 and 50: "))
if num >= 1 and num <= 50:
for num in range (1, 50):
if (num % 2 == 0):
print("Your number is even.")
else:
print("Your number is odd.")
else:
print("Try again. Number must be 1 through 50.")

我認為您根本不需要for回圈，并且else如果您的內部if-else：
while True:
num = int(input("Please enter an integer between 1 and 50: "))
if num >= 1 and num <= 50:
for num in range (1, 50): # not needed
if (num % 2 == 0):
print("Your number is even.")
else: # here
print("Your number is odd.")
else:
print("Try again. Number must be 1 through 50.")
for-else結構存在（并且非常簡潔），但是如果您開始學習 Python，這是另一個故事。

不，你不需要for回圈：
while True:
num = int(input("Please enter an integer between 1 and 50: "))
if 1 <= num <= 50:
if num % 2 == 0:
print("Your number is even.")
else:
print("Your number is odd.")
else:
print("Try again. Number must be 1 through 50.")

我認為您不需要 for 回圈，洗掉 for 回圈并重試。
while True:
num = int(input("Please enter an integer between 1 and 50: "))
if num >= 1 and num <= 50:
if (num % 2 == 0):
print("Your number is even.")
else: # here
print("Your number is odd.")
else:
print("Try again. Number must be 1 through 50.")
