我想重復詢問數字程序，而guess 與 TrueNum 不相等，但是當我將它放入 while 回圈時，它只是重復列印它的“if”我該怎么辦？
import random
# Defining True Num:
DataRange = list(range(0, 11))
TrueNum = int(random.choice(DataRange))
print("it`s in range from o to 10")
# Getting Guesses From User:
Guess = int(input("Input your number: "))
# Checking Guess:3
while Guess != TrueNum:
if Guess > TrueNum:
print("You Are Getting Far...")
elif Guess < TrueNum:
print("It`s bigger than you think :)")
break
if Guess == TrueNum:
print("yeah that`s it")

你需要把輸入放在while里面，也可以去掉一些不必要的條件：
import random
# Defining True Num:
DataRange = list(range(0, 11))
TrueNum = int(random.choice(DataRange))
print("it`s in range from o to 10")
# Getting Guesses From User:
Guess = int(input("Input your number: "))
# Checking Guess:3
while Guess != TrueNum:
if Guess > TrueNum:
print("You Are Getting Far...")
else:
print("It`s bigger than you think :)")
Guess = int(input("Input your number: "))
print("yeah that`s it")

使用 Try/Except 可以解決無效選擇，同時保持可讀性。
import random
# Defining True Num:
DataRange = list(range(0, 11))
TrueNum = int(random.choice(DataRange))
print("it`s in range from o to 10")
# Getting Guesses From User:
while True:
try:
Guess = int(input("Input your number: "))
if Guess > TrueNum:
print("You Are Getting Far...")
elif Guess < TrueNum:
print("It`s bigger than you think :)")
elif Guess == TrueNum:
print("yeah that`s it")
break
except ValueError:
print("Invalid Choice")

變數 Guess 定義在回圈外，您應該將輸入并檢查回圈內的值。
import random
datarange = list(range(0, 11))
trueNum = int(random.choice(datarange))
print("Guess the number! It`s in range from o to 10")
while True:
Guess = int(input("Input your number: "))
if Guess == trueNum:
print("Yeah that`s it")
break
elif Guess > trueNum:
print("You Are Getting Far...")
else:
print("It`s bigger than you think :)")
