在Python 3.6中，f-string更加简洁。

在早期版本中:

print("Total score for %s is %s. " % (name, score))

在Python 3.6中:

print(f'Total score for {name} is {score}.')

会做的事情。

它更加高效和优雅。

用途:.format ():

print("Total score for {0} is {1}".format(name, score))

Or:

// Recommended, more readable code

print("Total score for {n} is {s}".format(n=name, s=score))

Or:

print("Total score for" + name + " is " + score)

Or:

print("Total score for %s is %d" % (name, score))

或者:Python 3.6中的f-string格式:

print(f'Total score for {name} is {score}')

可以使用repr并自动添加“”:

print("Total score for" + repr(name) + " is " + repr(score))

# or for advanced: 
print(f'Total score for {name!r} is {score!r}') 

这可能是选角的问题。强制转换语法发生在试图组合两种不同类型的变量时。由于不能将字符串转换为整数或始终为浮点数，所以必须将整数转换为字符串。这就是你要做的。: str (x)。要转换为整数，它是:int(x)，浮点数是float(x)。我们的代码将是:

print('Total score for ' + str(name) + ' is ' + str(score))

也!运行此代码片段以查看如何转换不同类型变量的表格!

<table style="border-collapse: collapse; width: 100%;background-color:maroon; color: #00b2b2;"> <tbody> <tr> <td style="width: 50%;font-family: serif; padding: 3px;">Booleans</td> <td style="width: 50%;font-family: serif; padding: 3px;"><code>bool()</code></td> </tr> <tr> <td style="width: 50%;font-family: serif;padding: 3px">Dictionaries</td> <td style="width: 50%;font-family: serif;padding: 3px"><code>dict()</code></td> </tr> <tr> <td style="width: 50%;font-family: serif;padding: 3px">Floats</td> <td style="width: 50%;font-family: serif;padding: 3px"><code>float()</code></td> </tr> <tr> <td style="width: 50%;font-family: serif;padding:3px">Integers</td> <td style="width: 50%;font-family: serif;padding:3px;"><code>int()</code></td> </tr> <tr> <td style="width: 50%;font-family: serif;padding: 3px">Lists</td> <td style="width: 50%font-family: serif;padding: 3px;"><code>list()</code></td> </tr> </tbody> </table>

跟着这个

grade = "the biggest idiot"
year = 22
print("I have been {} for {} years.".format(grade, year))

OR

grade = "the biggest idiot"
year = 22
print("I have been %s for %s years." % (grade, year))

忘记所有其他的，否则大脑将无法映射所有的格式。

这就是我所做的:

print("Total score for " + name + " is " + score)

记住在for和is后面加空格。

最简单的方法如下

print(f"Total score for {name} is {score}")

只要在前面加个“f”就行了。
