Python在Print（）中的格式化

Question

要在Python中打印带有数学加数的字符串，正确的做法是：

# Read two inputs from users
a = input("Enter your First Number")
b = input("Enter your Second Number")

# perform type conversion
a = int(a)
b = int(b)

print (f"Result: {a}+{b}")

输出：

Enter your First Number10
Enter your Second Number10
Result: 10+10

所需的输出：Result: 20

Answer 1

您当前的格式字符串Result: {a}+{b}将a和b分别打印为Result: 10+10，并且不执行加法操作。

要实现此目的，您需要将f-string更改为f"Result: {a+b}"，以便在格式大括号内进行添加并打印结果

print (f"Result: {a+b}")

输出将为

Result: 20

Answer 2

a = input("Enter your First Number")
b = input("Enter your Second Number")

# perform type conversion
a = int(a)
b = int(b)

print (f"Result: {a + b}")

Answer 3

您应该更改

print (f"Result: {a} + {b}")

到

print (f"Result: {a + b}")

Answer 4
