是一个Python编程错误,表示在代码中试图将整数类型(int)隐式转换为字符串类型(str),但是Python不支持这种隐式转换。
在Python中,可以使用str()函数将整数转换为字符串。例如:
num = 123
str_num = str(num)
print(str_num) # 输出:'123'
如果想要将整数和字符串拼接在一起,可以使用字符串格式化或者f-string。例如:
num = 123
str_num = 'The number is ' + str(num)
print(str_num) # 输出:'The number is 123'
# 或者使用字符串格式化
str_num = 'The number is {}'.format(num)
print(str_num) # 输出:'The number is 123'
# 或者使用f-string(Python 3.6+)
str_num = f'The number is {num}'
print(str_num) # 输出:'The number is 123'
