Python 如何将数字转换为字符串
要将数字转换为字符串,有多种方法。让我们逐一来看看。
使用format()方法将数字转换为字符串
示例
在这个示例中,我们将使用format()方法将一个数字转换为字符串 −
# Integer to be converted
n = 60
# Display the integer and it's type
print("Integer = ",n)
print("Type= ", type(n))
# Convert the integer to string and display the type
myStr = "{}".format(n)
print("\nString = ", myStr)
print("Type = ", type(myStr))
输出
Integer = 60
Type= <class 'int'>
String = 60
Type = <class 'str'>
使用str()方法将数字转换为字符串
示例
在本示例中,我们将使用str()方法将一个数字转换为字符串−
# Integer to be converted
n = 25
# Display the integer and it's type
print("Integer = ",n)
print("Type= ", type(n))
# Convert the integer to string using str() and display the type
myStr = str(n)
print("\nString = ", myStr)
print("Type = ", type(myStr))
输出
Integer = 25
Type= <class 'int'>
String = 25
Type = <class 'str'>
将一个数字转换成字符串,使用%s格式
示例
在这个示例中,我们将使用%s格式说明符将一个数字转换成字符串。
# Integer to be converted
n = 90
# Display the integer and it's type
print("Integer = ",n)
print("Type= ", type(n))
# Convert the integer to string using %s and display the type
myStr = "% s" % n
print("\nString = ", myStr)
print("Type = ", type(myStr))
输出
Integer = 90
Type= <class 'int'>
String = 90
Type = <class 'str'>
使用str()将数字转换为字符串
示例
在这个示例中,我们将使用Python中的str()方法将数字转换为字符串。
# Integer to be converted
n = 150
# Display the integer and it's type
print("Integer = ",n)
print("Type= ", type(n))
# Convert the integer to string using __str__() and display the type
myStr = n.__str__()
print("\nString = ", myStr)
print("Type = ", type(myStr))
输出
Integer = 150
Type= <class 'int'>
String = 150
Type = <class 'str'>
使用f-string将数字转换为字符串
示例
在这个示例中,我们将使用f-string将一个数字转换为字符串 –
# Integer to be converted
n = 21
# Display the integer and it's type
print("Integer = ",n)
print("Type= ", type(n))
# Convert the integer to string using f-string and display the type
myStr = f'{n}'
print("\nString = ", myStr)
print("Type = ", type(myStr))
输出
Integer = 21
Type= <class 'int'>
String = 21
Type = <class 'str'>
