python字符串转浮点数

In the given example, we are printing different values like integer, float, string and Boolean using print() method in python.

在给定的示例中，我们使用python中的print()方法打印不同的值，例如整数，浮点数，字符串和布尔值。

Program:

程序：

# printing integer value 
print(12)
# printing float value 
print(12.56)
# printing string value 
print("Hello")
# printing boolean value 
print(True)

Output

输出量

12
12.56
Hello
True

Arithmetic operations inside the print() on values

在print()中对值进行算术运算

# adding and printing integer value 
print(12+30)
# adding and printing float value 
print(12.56+12.45)
# adding and printing string value 
print("Hello"+"World")
# adding and printing boolean value 
print(True+False)

Output

输出量

42
25.009999999999998
HelloWorld
1

Printing different types of variables

打印不同类型的变量

# variable with integer value
a=12
# variable with float value
b=12.56
# variable with string value
c="Hello"
# variable with Boolean value
d=True
# printing all variables 
print(a)
print(b)
print(c)
print(d)

Output

输出量

12
12.56
Hello
True

Printing different types of variables along with the messages

打印不同类型的变量以及消息

# variable with integer value
a=12
# variable with float value
b=12.56
# variable with string value
c="Hello"
# variable with Boolean value
d=True
# printing values with messages 
print("Integer\t:",a)
print("Float\t:",b)
print("String\t:",c)
print("Boolean\t:",d)

Output

输出量

Integer : 12
Float   : 12.56
String  : Hello
Boolean : True

Printing different types of variables with messages and converting them to string using "str()" function

使用消息打印不同类型的变量，并使用“ str()”函数将其转换为字符串

# variable with integer value
a=12
# variable with float value
b=12.56
# variable with string value
c="Hello"
# variable with Boolean value
d=True
# printing values with messages 
print("Integer\t:"+str(a))
print("Float\t:"+str(b))
print("String\t:"+str(c))
print("Boolean\t:"+str(d))

Output

输出量

Integer :12
Float   :12.56
String  :Hello
Boolean :True
