如何將int變量轉換為字符串

Question

這個問題是關於如何將int轉換為字符串的。我是編碼的新手，我不知道如何將int值轉換為str值，因為在python中，我們無法將int值與字符串值組合在一起。必須將int值轉換為string。 希望我的問題對自己和將來的編碼人員有幫助。

 print("Type your age ") character_age = input() print("So your age is "+character_age) print("If your father is 20 years older what will be your fathers age ?") age_character = int(character_age) print("Father's age is " +age_character) 

Answer 1

輸入：

print("Type your age ")
character_age = input()
print("So your age is "+character_age)
print("If your father is 20 years older what will be your fathers age ?")
age_character = int(character_age)+20 #add 20 with character age
print("Father's age is " + str (age_character )) # convert back into string for print

輸出：

Type your age
5
So your age is 5
If your father is 20 years older what will be your fathers age ?
Father's age is 25

Answer 2

您可以只使用int() ：

x = '10'
int(x)

如果要打印整數變量，則需要使用str()將其轉換回字符串，如最后一行所示：

print("Father's age is " + str(age_character))

Answer 3

print()引發TypeError。 您不能將string與int 。 您需要使用str函數將int轉換為string

print("Type your age ")
character_age = input()
print("So your age is "+character_age)
print("If your father is 20 years older what will be your fathers age ?")
age_character = int(character_age)
print("Father's age is " +str(age_character))

將print("Father's age is " +age_character)更改為：

print("Father's age is " +str(age_character))

要么

print("Father's age is",age_character)

Answer 4

您已經使用int構造函數正確地將字符串character_age轉換為整數，盡管要與其他字符串連接，您需要將其轉換回字符串，並且由於打印的消息顯示父親的年齡應該為20歲歲以上，在轉換為字符串之前，您需要添加20：

age_character = int(character_age) + 20
print("Father's age is " + str(age_character))

Answer 5

您是什么意思，您沒有得到想要的結果？

age_character = int(character_age)

age_character變量已將age轉換為int。 唯一的問題是您嘗試打印字符串和整數的組合。 您已將其轉換為字符串。

print(type(age_character))
print("Father's age is " + str(age_character) )

Answer 6

您不能使用'+'運算符直接打印整數，因為兩種數據類型都不同。 您需要將其轉換為字符串。嘗試以下操作即可。

print("Father's age is " + str(age_character))

其余代碼正確

Answer 7

您可以這樣操作（無需轉換為字符串）：確保您的（character_age必須為整數）

代碼：{{print“所以您的年齡是{character_age}”。format（character_age = character_age）}}

{{print“父親的年齡是{age_character}”。format（age_character = age_character）}}

Answer 8

Python的內置函數int()可用於此目的。

>>> a = "10"
>>> int(a)
10

但是，只要字符串是可轉換的，這可以工作。

>>> a = "45.2"
>>> int(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '45.2'
>>> b = "eleven"
>>> int(b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'eleven'
