Python articles --- exit for loop method: break and continue
In fact, the usage of break and continue to exit the for loop is the same as that of exiting while. break, when certain conditions are true, exit the loop, the following code is not executed, and terminate the entire loop; continue, when certain conditions are true, terminate the current loop and then execute the next loop. Let's use 2 code examples to see how to use it and the execution results.
1. break exits the for loop
Code example:
str1 = 'Python自学网'
for i in str1:
# 当某些条件成立退出循环,后面代码不执行,终止整个循环 ----break----条件:当i取到字符自
if i == '自':
break
print(i)
Results of the:
Second, continue exits the for loop
Code example:
str1 = 'Python自学网'
for i in str1:
# 当某些条件成立退出循环,后面代码不执行,终止整个循环 ----break----条件:当i取到字符自
if i == '自':
continue
print(i)
Results of the:
eg:
flag = ""
for i in range(10):
for x in "abc":
print(i, "---------", x)
if x == "b":
flag = True
break
if flag:
break
