Question

for (length, freq) in word_list:
    print(freq_temp.format(length, freq))
print("\n Len  Freq Graph")
for (length, freq) in word_list:
    graph_template = "{:>4}{:>5}% {}"
    number_symbol = "=" * percentage_frequency(freq, new_list)
    print(graph_template.format(length, percentage_frequency(freq, new_list),number_symbol))

您如何将这些for循环转换为while循环？

Answer 1

您错过了for和while循环this question does a good job of explaining it的意义。

基本上，for循环遍历列表，您可以对列表进行操作。

相反，while循环用于运行直到满足条件（例如触发标志）。

for循环：

mylist = ["this", "is", "a", "for", "loop"]
for element in mylist:
    print(element)

返回：

this
is
a
while
loop

while循环如下：

count = 0
while count != 10:
    print(count)
    count += 1
print("count has reached 10")

返回：

0
1
2
3
4
5
6
7
8
9
count has reached 10

总而言之，for循环用于遍历array或generator对象，其中while循环用于运行直到满足条件
