将整数“隐式”更改为字符串？？Python

Question

我想知道是否有人能帮我。我真的是新手，我需要把我的输入转换成一个字符串？你知道吗

# Python program to calculate the Fibonacci numbers
def fibR(n):
    if n == 1 or n == 2:
        return 1
    else:
        return fibR(n - 1) + fibR(n - 2)

# Request input from the user
num = int(input("Please enter the number in the Fibonacci sequence you wish to calculate: "))

#
if num == 1:
    print("The Fibonacci number you have requested is" + 1 + ".")
else :
    print("The Fibonacci number you have requested is" + fibR(num) + ".")

Answer 1

在else语句中使用%：

print("The Fibonacci number you have requested is %d." % fibR(num))
